A sprinkler manufacturer claims that the average activatingtemperatures is at least 132 degrees. To test this claim, yourandomly select a sample of 32 systems and find the mean activationtemperature to be 133 degrees. Assume the population standarddeviation is 3.3 degrees. Find the standardized test statistic andthe corresponding p-value.

z-test statistic = -1.71, p-value = 0.0865
z-test statistic = 1.71, p-value = 0.0865
z-test statistic = -1.71, p-value = 0.0432
z-test statistic = 1.71, p-value = 0.0432

A consumer group claims that the mean acceleration time from 0to 60 miles per hour for a sedan is 7.0 seconds. A random sample of33 sedans has a mean acceleration time from 0 to 60 miles per hourof 7.6 seconds. Assume the population standard deviation is 2.3seconds. Find the standardized test statistic and the correspondingp-value.

z-test statistic = -1.499, p-value = 0.067
z-test statistic = -1.499, p-value = 0.134
z-test statistic = 1.499, p-value = 0.067
z-test statistic = 1.499, p-value = 0.134

A consumer research organization states that the mean caffeinecontent per 12-ounce bottle of a population of caffeinated softdrinks is 37.8 milligrams. You find a random sample of 48 12-ouncebottles of caffeinated soft drinks that has a mean caffeine contentof 35.2 milligrams. Assume the population standard deviation is12.5 milligrams. At ?=0.05, do you support or reject theorganization’s claim using the test statistic?

Claim is null, reject the null and reject claim as teststatistic (-1.44) is in the rejection region defined by thecritical value (-1.96)
Claim is alternative, fail to reject the null and support claimas test statistic (-1.44) is not in the rejection region defined bythe critical value (-1.64)
Claim is alternative, reject the null and reject claim as teststatistic (-1.44) is in the rejection region defined by thecritical value (-1.64)
Claim is null, fail to reject the null and support claim astest statistic (-1.44) is not in the rejection region defined bythe critical value (-1.96)
