Independent-samples t test statistical test is most appropriate for analyzing the results .

What is Independent-samples t test?

To ascertain whether there is statistical support that the linked population means are statistically substantially different, the Independent Samples t Test compares the means of two independent groups.

                     An example of a parametric test is the Independent Samples t Test. The Independent t Test is another name for this test.

What is the difference between a dependent and independent samples t-test?

If the participants in one sample do not influence the participants in the other, then the two (or more) samples are said to be independent.

                                  Dependent samples are two (or more) samples where the members picked for one sample automatically determine the members chosen for the second sample.

The volume of the cube with the shortest possible side lengths is 216 cubic inches.

If a steel sphere with a 3-inch radius is made by removing metal from the corners of a cube that has the shortest possible side lengths, then the side lengths of the cube must be equal to the diameter of the sphere.

side length of cube = diameter of sphere

side length of cube = 2 x radius of sphere

side length of cube = 2 x 3 inches

side length of cube = 6 inches

The volume of the cube can be calculated using the formula below.

7. the graphed solution (bold line) shows inequalities x≥-1

this is the same as inequality: x + 1 ≥ 0 (A)

a. Probability that there are minor fraudulent activities in fewer than 2 out of 100 transactions is 0.1761

b. Using the table, we get the value of probability that there are serious fraudulent activities in fewer than 2 out of 100 transactions  0.9695.

When it comes to fraud detection, it is a necessary tool for banks and credit card companies to help fight fraudulent credit card transactions.

Fraudulent activities have been detected by a fraud detection firm at a rate of 1.31 percent in minor cases and 0.87 percent in serious cases.

To solve this question, we must follow the steps below:

We have to use the binomial distribution formula for solving this question.

The formula for the binomial distribution is: \(P (x) = C (n, x) * p^x * q^(n-x)\)

Where, n = number of trials,

x = number of successes,

p = probability of success,

and q = probability of failure.

Here, for minor fraudulent activities, probability of success,

p = 0.0131;

probability of failure,

q = 1 - 0.0131

= 0.9869;

n = 100.

Thus, for part a, we have to find P (x < 2) = P (0) + P (1).

Now, using the formula mentioned above: \(P (0) = C (100, 0) * (0.0131)^0 * (0.9869)^(100-0) = 0.8581\)

\(P (1) = C (100, 1) * (0.0131)^1 * (0.9869)^(100-1)\)

\(= 0.3172P (x < 2) = P (0) + P (1) = 0.8581 + 0.3172 = 1.1753\)

We can't have a probability greater than 1, so this answer doesn't make sense.

Thus, we have to find 1 - P (x > 1) = 1 - [P (2) + P (3) + ... + P (100)].

We can use the cumulative binomial distribution table to calculate this probability.

We have n = 100 and p = 0.0131. Using the table, we get the value of 0.1761.

b. Probability that there are serious fraudulent activities in fewer than 2 out of 100 transactions is 0.9695.

We will be solving this part using a similar approach as we used in part

a. Probability of success,

p = 0.0087; probability of failure, q = 1 - 0.0087 = 0.9913;

n = 100.

Now, for part b, we have to find P (x < 2) = P (0) + P (1).

Using the formula mentioned above:

\(P (0) = C (100, 0) * (0.0087)^0 * (0.9913)^(100-0)\)

\(= 0.9131P (1)\)

\(= C (100, 1) * (0.0087)^1 * (0.9913)^(100-1)\)

\(= 0.0839P (x < 2)\)

= P (0) + P (1)

= 0.9131 + 0.0839

= 0.9970

We can use the cumulative binomial distribution table to calculate \(1 - P (x > 1) = 1 - [P (2) + P (3) + ... + P (100)].\)

We have n = 100 and p = 0.0087.

Using the table, we get the value of 0.9695.

Using the arc length measurements the value for m ∠RWV is obtained as 115°.

What is arc length?

The distance between two places in a curve's section is known as the arc length. Any portion of a circle's circumference is an arc.

The measure of arc length VR is given as x + 122.

The measure of arc length RS is given as x + 72.

So, the measure of arc length VS is given as x + 122 + x + 72.

Now, since line segment VS is the diameter of the circle so, we can mathematically write that -

x + 122 + x + 72 = 180°

Solving this equation we get -

2x + 194 = 180

2x = -14

x = -7

Now, from the given figure, the measure of ∠RWV will be -

∠RWV = x + 122

Substitute the value of x in the equation -

∠RWV = -7 + 122

∠RWV = 115°

Therefore, the measure value is ∠RWV = 115°.

In statistical hypothesis testing, a Type I error is a mistake made by rejecting a null hypothesis when it is valid. It is also known as a false-positive error.b. 95% confidence interval is wider than the 90% confidence interval - True. When compared to a 90% confidence interval, a 95% confidence interval is wider. The probability of capturing the actual population mean is higher with the wider interval. c. As the sample size increases, the width of the 95% confidence interval increases - False.

As the sample size increases, the width of the confidence interval decreases. d. Population mean μ is a statistic - False. μ is the symbol for the population mean, which is a parameter, not a statistic. e. As type I error increases Type II error also increases - True. Increasing the probability of making a Type I error also increases the probability of making a Type II error. These two types of errors are inversely proportional to each other.

  The ant's entire distance travelled along its semicircular journey is its total distance travelled overall. The ant is travelling around a circle with radius R, thus the distance it has travelled is equal to half of the circle's circumference, πR.

The change in the ant's position is represented by a vector quantity called the displacement of the ant. The ant in this scenario begins at one end of the semi-circular path and moves 2R away from the beginning point to reach the other end. The direction of the displacement vector is from the starting point to the ending point, and the displacement's magnitude is equal to the 2R distance between the two points.

    So, the option c is most suitable option.

Therefore, πR and 2R are the ant's displacement and the distance travelled, respectively.

C. The value of b for which the equation (ye3xy+x)dx+bxe3xydy=0 is exact is b = 1/3. Using this value of b, the equation can be solved.

A. To check if the equation (5x+3)+(5y−5)y′=0 is exact, we compute the partial derivatives with respect to x and y. If the mixed partial derivatives are equal, the equation is exact. However, in this case, the mixed partial derivatives are not equal, indicating that the equation is not exact.

B. For the equation (yx+3x)dx+(ln(x)−4)dy=0, we calculate the partial derivatives and find that they are equal, indicating that the equation is exact. To solve it, we can find an integrating factor, which in this case is e^(∫(1/x)dx) = e^ln(x) = x. Multiplying the equation by the integrating factor, we get x(yx+3x)dx+x(ln(x)−4)dy=0. Integrating both sides with respect to x, and treating y as a constant, we obtain the solution.

C. To find the value of b for which the equation (ye3xy+x)dx+bxe3xydy=0 is exact, we compare the coefficients of dx and dy and equate them to zero. This leads to the condition b = 1/3.

5. lastly, put them together as a fraction

The probability P(X=2, Y+Z ≤ 3) is 13. Random variables are variables in probability theory that represent the outcomes of a random experiment or event.

To find the probability P(X=2, Y+Z ≤ 3), we need to sum up the joint probabilities of all possible combinations of X=2, Y, and Z that satisfy the condition Y+Z ≤ 3.

Step 1: List all the possible combinations of X=2, Y, and Z that satisfy Y+Z ≤ 3:

X=2, Y=1, Z=1

X=2, Y=1, Z=2

X=2, Y=2, Z=1

Step 2: Calculate the joint probability for each combination:

For X=2, Y=1, Z=1:

f(2, 1, 1) = (2+1) * 1 = 3

For X=2, Y=1, Z=2:

f(2, 1, 2) = (2+1) * 2 = 6

For X=2, Y=2, Z=1:

f(2, 2, 1) = (2+2) * 1 = 4

Step 3: Sum up the joint probabilities:

P(X=2, Y+Z ≤ 3) = f(2, 1, 1) + f(2, 1, 2) + f(2, 2, 1) = 3 + 6 + 4 = 13

We can conclude that the volume of cylinder 1 is 3/4 times the volume of cylinder 2.

The volume of cylinder is given by -

V = πR²h

Given is to compare the volume of a cylinder with a radius of 6 inches and a height of 8 inches compare to the volume of a cylinder with a radius of 8 inches and a height of 6 inches.

Volume of cylinder 1 will be -

V(1) = πR²h = 6 x 6 x 8π = 36 x 8π = 288π

Volume of cylinder 2 will be -

V(2) = πR²h = 8 x 8 x 6π = 64 x 6π = 384π

So, we can write that -

V(1)/V(2) = (288π)/(384π)

V(1)/V(2) = (288)/(384)

V(1)/V(2) = 3/4

Therefore, we can conclude that the volume of cylinder 1 is 3/4 times the volume of cylinder 2.
