B. Solve the problems by following the step-by-step procedure in hypothesis testing.1. A soda manufacturer is interested in determining whether its bottling machine tends tooverfil. Each bottle is supposed to contain 12 ounces of fluid. A random sample of 25 bottleswas taken and found that the mean amount of soda of the sample of bottles is 11.4 ounceswith a standard deviation of 0.6 ounces. If the manufacturer decides on a significance levelof 0.05 test, should the null hypothesis be rejected?

Assume a significance level of a = 0.01 and use the given information to complete parts (a) and (b) below. Original claim: The standard deviation of pulse rates of a certain group of adult males is more than 14 bpm. The hypothesis test results in a P-value of 0.3989. a. State a conclusion about the null hypothesis. (Reject Ho or fail to reject Ho.) Choose the correct answer below. O A. Reject Ho because the P-value is less than or equal to a. O B. Fail to reject Ho because the P-value is greater than a. O C. Rejecdo because the P-value is greater than a. O D. Fail to reject Ho because the P-value is less than or equal to . b. Without using technical terms, state a final conclusion that addresses the original claim. Which of the following is the correct conclusion? O A. There is not sufficient evidence to support the claim that the standard deviation of pulse rates of the group of adult males is more than 14 bpm. O B.

A survey found that women's heights are normally distributed with mean 62.3 in. and standard deviation 2.3 in. The survey also found that men's heights are normally distributed with mean 68.4 in. and standard deviation 3.7 in. Consider an executive jet that seats six with a doorway height of 56.4 in. Complete parts (a) through (c) below. a. What percentage of adult men can fit through the door without bending? The percentage of men who can fit without bending is %. (Round to two decimal places as needed.) b. Does the door design with a height of 56.4 in. appear to be adequate? Why didn't the engineers design a larger door? O A. The door design is adequate, because although many men will not be able to fit without bending, most women will be able to fit without bending. Thus, a larger door is not needed. O B. The door design is inadequate, because every person needs to be able to get into the aircraft without bending. There is no reason why this should not be implemented. O C. The door…
