Step-by-step explanation:

The most restrictive level of significance that would suggest the company should raise rates is a p-value less than or equal to 0.01.

Hypothesis testing is a statistical method that is used to make decisions about a population based on a sample of data.

It involves testing a null hypothesis (H0) against an alternative hypothesis (Ha) using statistical techniques.

We have,

To determine if the increase in the average cost per claim is statistically significant, we can perform a hypothesis test.

Let's use a one-sample t-test, where:

Null hypothesis (H0): The average cost per claim is still $2,200.

Alternative hypothesis (Ha): The average cost per claim is greater than $2,200.

We can use a t-test because we have a sample mean, sample size, and population standard deviation.

The test statistic is calculated as:

t = (sample mean - hypothesized mean) / (standard deviation/√ (sample size))

Plugging in the values given, we get:

t = (2350 - 2200) / (500 / √(40))

t = 4.38

Using a t-table with degrees of freedom (df) = 39 (sample size - 1), we can find the p-value associated with this test statistic.

At the 0.01 level of significance (most restrictive level), the critical t-value is 2.704.

Since our calculated t-value is greater than the critical t-value, we reject the null hypothesis and conclude that there is evidence to suggest that the average cost per claim has increased.

Therefore,

The most restrictive level of significance that would suggest the company should raise rates is a p-value less than or equal to 0.01.

Experimental and quasi-experimental designs share similarities in terms of their focus on investigating cause-and-effect relationships. These designs both involve manipulating variables and observing their effects on an outcome of interest.

However, they differ in terms of the level of control the researcher has over the assignment of participants to groups. Experimental designs are characterized by the random assignment of participants to different groups or conditions. This randomization helps ensure that any observed differences between groups can be attributed to the manipulation of the independent variable. The researcher has control over the assignment process, allowing for stronger causal inferences. Quasi-experimental designs, on the other hand, lack the random assignment of participants to groups. This may be due to practical or ethical reasons. Instead, participants are assigned to groups based on pre-existing characteristics, such as age or location. While quasi-experimental designs still allow for the examination of cause-and-effect relationships, they are considered less rigorous than experimental designs due to the potential for confounding variables. In summary, experimental and quasi-experimental designs both aim to investigate cause-and-effect relationships. They differ primarily in the level of control the researcher has over participant assignment. Experimental designs use random assignment for greater control, while quasi-experimental designs rely on pre-existing characteristics.

Answer: A good way to get a small standard error is to use a large sample.

Step-by-step explanation:

In order to find the small standard error, there is always need of a complete set which is called the large sample.

If tried to do a small or repeating sample, you will most likely not get an error and you could get a repetition. If you do a population sample, you wont get accurate results at all.

Therefore, a good way to get a small standard error is to use a large sample. Hope this helps!

With dilation at center (0,0) and a scale factor of 5, the coordinates as we can see from given graph are Q(-3,4), R(-2,-1), T(3,1), W(3,5).

What exactly is dilation?

Dilation is the process of modifying the size of an item or form by reducing or expanding its dimensions according to specific scaling variables. A circle of radius 10 unit, for example, is reduced to a circle with radius 5 unit. This approach is utilised in photography, arts and crafts, and the creation of logos, among other things. There are four primary types of transformations in geometry. They are as follows:

If in triangle ABC, AD and BE are medians, and AD and BE are also bisectors, then triangle ABC is an equilateral triangle.

In the given scenario, we have triangle ABC with medians AD and BE, which intersect at a point called the centroid. Additionally, it is stated that AD and BE are also bisectors, meaning they divide the angles of the triangle into two equal parts.

First, let's consider the medians AD and BE. Medians divide each side of the triangle into two equal segments, and they intersect at the centroid, which is also the center of gravity of the triangle. The centroid divides each median in a 2:1 ratio, meaning that the distance from the centroid to a vertex is twice the distance from the centroid to the midpoint of the opposite side.

Next, since AD and BE are bisectors, they divide the angles of the triangle into two equal parts. This implies that each angle of the triangle is bisected, resulting in three congruent angles.

By combining the properties of medians and bisectors, we conclude that all three sides of triangle ABC are congruent. Therefore, triangle ABC is an equilateral triangle, where all angles are congruent and all sides have the same length.

Answer:

TRUE

Step-by-step explanation:

The probability of committing a type 1 error is called alpha (or the level of statistical significance)

Alpha is the probability of committing a type i error. The statement is True.

Alpha is also known as the level of significance. In hypothesis testing, the level of significance is used to determine the acceptance or rejection of a null hypothesis. It's calculated by dividing the critical value (the value beyond which we can reject the null hypothesis) by the standard deviation of the population. The level of significance is typically set to 0.05 or 0.01. If the p-value (the probability of getting the observed results by chance) is less than the level of significance, we reject the null hypothesis and conclude that the alternative hypothesis is true.

Therefore, it's true that alpha is the probability of committing a type I error, which occurs when we reject a null hypothesis that is actually true. A type I error is also known as a false positive. In other words, we conclude that there is a significant effect or relationship when there isn't one. The level of significance is a measure of how willing we are to make this type of error. If we set a high level of significance, we are more likely to make a type I error.

502.4 cubic unit

Step-by-step explanation:

Given data

The parameter for the cylinder is as follows

Height h= 10units

Radius r= 4 units

We know that the expression for the volume of a cylinder is

V= πr^2h

substitute

V= 3.14*4^2*10

V= 3.14*16*10

V= 502.4 cubic unit

Hence the volume is  502.4 cubic unit

The question is asking for the roots of the polynomial f(x) = 5x4 - 2x3 - 25x2 - 6x + 45. Therefore, the roots of f(x) = 5x4 - 2x3 - 25x2 - 6x + 45 are approximately -1.2 and 1.6.

To find the roots of a polynomial, we need to set f(x) equal to zero and solve for x. This means we are looking for values of x that make the equation f(x) = 0 true. We can do this through factoring or by using numerical methods such as the quadratic formula or Newton's method. To find the roots of f(x) = 5x4 - 2x3 - 25x2 - 6x + 45, we can use various methods. One approach is to try to factor the polynomial.

However, it is not immediately clear how to factor this polynomial, so we can turn to numerical methods. One way to find the roots is to use a graphing calculator or software to plot the function and look for the x-intercepts (where the function crosses the x-axis). This can give us an approximate idea of where the roots are located. Another method is to use iterative numerical techniques such as Newton's method or the bisection method to find the roots with increasing accuracy.

Her total commission was $560.

As 10% of the first $1,000, 15% of the next $2,000, and 20% of sales beyond $3,000 are commissions that she receives. She sold $3,400 worth of tires last week.

What does "total commission" mean?

The commission serves as a benefit or an inducement for the worker to close agreements so that the business can increase revenue and profits. The total commission is calculated by multiplying the total sales by the commission percentage.

After dividing the outcome by 100, multiply the sale price by the commission percentage. Perform the subsequent calculation: Each blue gadget costs $70. The salesman receives a 14% commission on each sale, or $9.80.

The percentage or fixed payment connected to a specific number of sales is referred to as a "commission rate." A commission, for instance, can be $30 or 6% of sales.

STEPS to find the find the scale factor given a center of dilation an image and a Preimage are given below

What is Scale factor, pre-image and dilation?

Dilation: A dilation is a stretch or a contraction in a figure or point's size and placement.

Resizing an item uses a transition called dilation. Dilation is used to enlarge or contract the items. The result of this transformation is a picture with the same shape as the original. However, there is a variation in the shape's size. The initial form should be stretched or contracted during a dilatation. The phrase "scale factor" describes this transition.

Scale Factor: In a dilatation, the scale factor refers to how much the figure is enlarged or contracted.

Step 1:

By comparing the length of one side of the pre-image to the corresponding side of the post-image, one may determine the dilation scale factor. The pre-image must be multiplied by the scaling factor to equal the post-image. If the side of the pre-image is the length of \(lpre\)and the length of the corresponding side of the post-image is \(lpost\),

, then the scale factor is given by k in the equation  =  \(lpre\) \(k\)=\(lpost\).

We can solve for k algebraically.

Step 2:-

Choose a matching group of spots on the pre-image and picture. the main point

(x1,y1) being the focal point of the pre-image (x2,y2) be the Centre of the enlarged picture.

By resolving the following two equations, you may get the coordinates of the Centre of dilation,
