The correct option  is:

She cannot reject the null hypothesis at α = 0.05 because 7.5 is not contained in the 95% confidence interval.

Option B is correct

A confidence interval is described as a range of estimates for an unknown parameter. A confidence interval is also computed at a designated confidence level; the 95% confidence level is most common, but other levels, such as 90% or 99%, are sometimes used.

For the true population mean, a confidence interval provides a range of likely values, and in this instance, the 95% confidence interval is (5.8, 6.4).

Thus, if we were to conduct this study repeatedly, we could anticipate that the genuine population mean would, 95% of the time, fall between 5.8 and 6.4.

The rate of change of the area of the square at that instant is approximately -22.1978 square kilometers per hour.

Let's start by recalling the formula for the area of a square: A = \(s^2,\)where A is the area and s is the side length. We are given that the side length is decreasing at a rate of 2.22 kilometers per hour. This means that the rate of change of the side length is ds/dt = -2.22 km/h (the negative sign indicates that the side length is decreasing).

At a certain instant, the side length is 9.99 kilometers. We can use this information to find the area of the square at that instant:

A = \(s^2 = (9.99 km)^2 = 99.8001 km^2\)

To find the rate of change of the area at that instant, we can use the chain rule of differentiation:

dA/dt = dA/ds * ds/dt

We know ds/dt = -2.22 km/h, and we can find dA/ds by differentiating the formula for the area:

dA/ds = 2s

So, at the instant when the side length is 9.99 km, the rate of change of the area is:

dA/dt = dA/ds * ds/dt = 2s * (-2.22 km/h) = -22.1978\(km^2/h\)

Therefore, the rate of change of the area of the square at that instant is approximately -22.1978 square kilometers per hour.

A(n) experiment can be used to establish a cause and effect relationship between the explanatory and response variables.

In an experiment, researchers actively manipulate the explanatory variable (also known as the independent variable) to observe its effect on the response variable (also known as the dependent variable). By controlling and manipulating the conditions of the experiment, researchers can establish a cause and effect relationship between the variables.

The key characteristic of an experiment is the ability to assign participants or subjects randomly to different treatment groups. This random assignment helps ensure that any observed effects on the response variable are due to the manipulation of the explanatory variable and not due to other confounding factors.

By conducting experiments, researchers can gather strong evidence to support or refute hypotheses about causal relationships. The experimental design allows for rigorous control over potential sources of bias and provides a foundation for drawing conclusions about cause and effect.

It is important to note that while experiments are powerful in establishing causality, they may not always be feasible or ethical for certain research questions. In such cases, other study designs, such as observational studies, can provide valuable insights, but establishing causal relationships becomes more challenging.

Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:

Sum of exterior angles of any Polygon = 360°

23.  x + 65 + 106 + 78 = 360

                    x  + 249   = 360    

{To find the value of x, subtract 249 from both sides}

                               x    = 360 - 249

                                  x = 111°

_________________________________________

24.  x + x + 59 + 48 + 50 + 39 + 58 = 360

                                       2x + 254   = 360

                                                    2x = 360 - 254

                                                    2x = 106

                                                       x = 106 ÷ 2

                                                       x = 53°

____________________________________________

25. 2x + 3x + 44 +85 + 71 = 360

                         5x + 200  = 360

                                    5x  = 360 - 200

                                     5x = 160

                                       x = 160 ÷ 5

                                       x = 32°

_______________________________________________

26.  x+ 2x + 77 + 40 + 45 = 360

                          3x +  162 = 360

                                    3x  = 360 - 162

                                    3x  = 198

                                      x = 198 ÷ 3

                                     x = 66°

The probability that the sample mean will be less than 200 pounds is approximately 0.9015 or 90.15%.

Step-by-step explanation:

To solve this problem, we can use the central limit theorem, which states that the sampling distribution of the mean of a large sample (n >= 30) will be approximately normal, regardless of the distribution of the population.

We are given that the population mean is 196 pounds and the standard deviation is 22 pounds. The sample size is 50, which is large enough to apply the central limit theorem.

To find the probability that the mean of the sample will be less than 200 pounds, we need to standardize the sample mean using the formula:

z = (x - mu) / (sigma / sqrt(n))

where x is the sample mean, mu is the population mean, sigma is the population standard deviation, and n is the sample size.

Plugging in the values we get:

z = (200 - 196) / (22 / sqrt(50)) = 1.59

Now we need to find the probability that a standard normal variable is less than 1.59. We can use a standard normal table or calculator to find this probability, which is approximately 0.944.

Therefore, the probability that the mean of the sample will be less than 200 pounds is 0.944 or 94.4% (rounded to one decimal place).

So, we can say that there is a 94.4% chance that the mean weight of 50 randomly selected individuals will be less than 200 pounds.

The value of a(t) is -1 and b(t) is 55 + \(e^t\)

No, the given equation y' - y = 55 + \(e^t\) is not in the standard form of a first-order linear differential equation.

In the method for solving a first-order linear differential equation, an integrating factor is a function used to transform the equation into a form that can be easily solved.

For an equation in the standard form y' + a(t)y = b(t), the integrating factor is defined as:

μ(t) = e^∫a(t)dt

To solve the equation, you multiply both sides of the equation by the integrating factor μ(t) and then simplify. This multiplication helps to make the left side of the equation integrable and simplifies the process of finding the solution.

To put it in standard form, we need to rewrite it as y' + a(t)y = b(t).

Comparing the given equation with the standard form, we can identify:

a(t) = -1

b(t) = 55 + \(e^t\)

Therefore, The value of a(t) is -1 and b(t) is 55 + \(e^t\)

When two expressions are connected with the equals sign (=) in a mathematical formula, it expresses the equality of the two expressions. In English, an equation is defined as a properly written formula that consists of two expressions joined by an equals sign, while cognates of the word in other languages may have slightly different meanings. An equation, for instance, is said to have one or more variables in French.

Determine which values of the variables result in the equality to be true in order to solve an equation with variables. The values of the variables that must fulfill the equality to constitute the answer are known as the unknowns, together with the variables for which the equation must be solved.

Let x be the number of blocks of one inch

And y be the number of three inch blocks

To find the perimeter of a trapezoid, you simply add up the lengths of all four sides.

In this case, the trapezoid has sides of 8 cm, 10 cm, 16 cm, and 10 cm.

Perimeter = 8 cm + 10 cm + 16 cm + 10 cm

Perimeter = 44 cm

Therefore, the perimeter of the trapezoid is 44 cm.

The solution with the lesser x is -10 and the solution with the greater x is -2.

The given function is f(x) = (x+6)² - 16.

To find the zeros of the function, we need to set f(x) equal to zero and solve for x.

0 = (x+6)² - 16

Adding 16 to both sides, we get:

16 = (x+6)²

Taking the square root of both sides, we get:

±4 = x+6

Subtracting 6 from both sides, we get:

x = -6 ± 4

Therefore, the zeros of the function are x = -10 and x = -2.

Step-by-step explanation:

The manufacturer should offer a replacement guarantee period of approximately 8.012 years. This means that if a carpet cleaner fails within this period, the manufacturer will replace it.

To determine the replacement guarantee period for the carpet cleaners, the manufacturer needs to find the value that corresponds to the 16th percentile of the normal distribution with a mean of 10 years and a standard deviation of 2 years. This value represents the number of years after which 16% of the carpet cleaners are expected to fail.

Using a standard normal distribution table or a statistical calculator, the manufacturer can find the z-score associated with the 16th percentile. The z-score represents the number of standard deviations away from the mean that corresponds to the desired percentile. Once the z-score is obtained, it can be multiplied by the standard deviation and added to the mean to find the number of years for the replacement guarantee period.

For example, if the z-score corresponding to the 16th percentile is -0.994, the manufacturer would calculate the replacement guarantee period as follows:

Replacement guarantee period = Mean + (Z-score * Standard Deviation)

= 10 + (-0.994 * 2)

= 10 - 1.988

= 8.012

Therefore, the manufacturer should offer a replacement guarantee period of approximately 8.012 years. This means that if a carpet cleaner fails within this period, the manufacturer will replace it.
