State the conclusion based on the results of the test. The mean of the pressure required to open a certain valve is known to be = 7.9 psi. Due to changes in the manufacturing process, the quality-control manager feels that the average pressure has changed. The null hypothesis was rejected. Choose thee correct answer below. OA. There is not sufficient evidence that the mean of the pressure required to open a certain valve has changed. O B. The mean of the pressure has not changed. Oc. The mean of the pressure has changed. OD. There is sufficient ovidence that the mean of the pressure required to open a certain valve has changed. OE. There is sufficient evidence that the mean of the pressure required to open a certain valve has not changed. OF There is not suficient evidence that the mean of the pressure required to open a certain valve has not changed.
To compare the dry braking distances from 30 to 0 miles per hour for two makes of automobiles, a safety engineer conducts braking tests for 35 models of Make A and 35 models of Make B. The mean braking distance for Make A is 45 feet. Assume the population standard deviation is 4.6 feet. The mean braking distance for Make B is 46 feet. Assume the population standard deviation is 4.3 feet. At a= 0.10, can the engineer support the claim that the mean braking distances are different for the two makes of automobiles?

On average, a coffee machine fills into 214 milliliter cups. Sometimes, the machine makes errors with an estimated variance of 81. What is the standardized score for a randomly selected coffee cup that measured 250 milliliters? Answer:
The average triglyceride level of adult males is 126 milligrams per deciliter. You want to determine whether the true mean male triglyceride level is more than the average. You decide to pull a random sample of eight adult males and measure their triglyceride level. You find the sample mean is 127.9 milligrams per deciliter and the standard deviation is 4.12 milligrams per deciliter. What are the test statistic and the p-value? O The test statistic is 1.9 and the p-value is 0.1174. O The test statistic is 0.1174 and the p-value is 1.9. O The test statistic is 1.46 and the p-value is 1.30. O The test statistic is 0.1174 and the p-value is 1.30. O The test statistic is 1.30 and the p-value is 0.1167.

For a medical study, a researcher wishes to select people in the middle 60% of the population based on blood pressure. Assuming that blood pressure readings are normally distributed and the mean systolic blood pressure is 120 and the standard deviation is 8, find the upper and lower readings that would qualify people to participate in the study. Draw a normal curve then shade the needed area and indicate the z-value (or z-score).

A company makes high-definition televisions and does not like to have defective pixels. Historically,the mean number of defective pixels in a TV is 20. An engineer is hired to make better TV’s that havefewer defective pixels. After his first week of work he claims that he can significantly improve the currentmethod. To check his claim you try his new method on 100 new televisions. The average number ofdefective pixels in those 100 TV’s is 19.1. Assume that the new method doesn’t change the standarddeviation of defective pixels, which has always been 4.(a) Test if the new method is significantly better than the old one at the α = 0.05 level.(b) Using the new method, assume that the mean number of defective pixels is actually 19. What is thechance that your test from part 1 will conclude that the new method is statistically more effective?
Matthew wants to estimate the mean fat content of a pack of potato chips manufactured by UniBee Foods. He wants to be 90% confident that the estimate is accurate within 0.5 mg. Old records showed a 1.2 mg standard deviation. What should be the minimum sample size that he needs to construct this estimate?
