A laboratory wants to acquire a new centrifugal pump for ammonia. Thespecification indicates that the flow rate be more than 5 gallons perminute (gpm). In a preliminary study, 8 runs were made. The averageflow rate was 6.5 gpm and the standard deviation was 1.9 gpm. If themean flow rate is found to meet the specification, the pump will be putinto service. If the null hypothesis is set to H0 : μ=5 gpm, what is the mostappropriate alternative? What is the calculated statisticfor this problem? What is the critical value forα =0 . 05 and would we reject the null hypothesis?

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 43 feet. Assume the population standard deviation is 4.7 feet. The mean braking distance for Make B is 44feet. Assume the population standard deviation is 4.5 feet. At α=0.10, can the engineer support the claim that the mean braking distances are different for the two makes of automobiles? Assume the samples are random and independent, and the populations are normally distributed. Complete parts (a) through (e). a) identify the claim and state Ho and Ha b) find the critical values and identify the rejection regions c) Find the standardized test statistic z d) Decide whether to reject or fail to reject the null hypothesis. e) Interpret the decision in the context of the original claim.
The axial load of an aluminum can is the maximum weight the sides can support before giving way. A soft drink manufacturer is testing aluminum cansthinner. A sample of 77 of these cans provided an average axial load equal to 48.72pounds. It is known that currently used cans have an average load of 48 pounds and astandard deviation of 23.23 pounds. Assuming the manufacturer wants to test whether the axial loadaverage of thinner cans is 48 against the hypothesis that average axial load of thinner cansfines is less than 48, tick the alternative corresponding to the p-value for the test.

Suppose a golfer claims that her drive distance is not equal to 232 meters, on average. Several of her friends do not believe her, so the golfer decides to do a hypothesis test, at a 10% significance level, to persuade them. She hits 21 drives. The mean distance of the sample drives is 239 meters. The golfer knows from experience that the standard deviation for her drive distance is 15 meters. H0: μ=232; Ha: μ≠232 α=0.1 (significance level) What is the test statistic (z-score) of this one-mean hypothesis test, rounded to two decimal places?
A study of the amount of time it takes a mechanic to rebuild the transmission for a 2005 Cheverolet Cavalier shows that the mean is 8.4 hours and the standard devition is 1.8 hours. If 40 mechanics are randomly selected, find the probatility that their mean rebuild time exceeds 8.7 hours.
