An incubation period is a time between when you contract a virus and when your symptoms start. Assume that the population of incubation periods for a novel coronavirus has an unknown population standard deviation. By surveying randomly selected local hospitals, a researcher was able to obtain a sample of incubation periods of 40 patients with the average of the data of 9 days and the standard deviation of 3 days. At 10% significance level, test the claim that the average incubation period of the novel coronavirus is different from 7 days.
A leasing firm claims that the mean number of miles driven annually, µ, in its leased cars is less than 12,300 miles. A random sample of 80 cars leased from this firm had a mean of 12,150 annual miles driven. It is known that the population standard deviation of the number of miles driven in cars from this firm is 3160 miles. Is there support for the firm's claim at the 0.05 level of significance? Perform a one-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places, and round your responses as specified below.

An electric lamps manufacturer is testing a new method of producing lamps that will be considered acceptable in a normal population with an average life of 2600 hours and a standard deviation equal to 350. A sample of 80 lamps produced by this method has an average life of 2630 hours. Can the hypothesis of validity for the new manufacturing process be accepted with a risk equal to or less than 5%
A leasing firm claims that the mean number of miles driven annually, µ, in its leased cans is less than 12460 miles. A random sample of 27 cars leased from this firm had a mean of 11839 annual miles driven. It is known that the population standard deviation of the number of miles driven in cars from this firm is 1620 miles. Assume that the population is normally distributed. Is there support for the firm’s claim at the 0.05 level of significance? The null hypothesis: H0 : _____ The alternative hypothesis: H1: ______ The type of test statistic: (choose one) _______ The value of the test statistic: ______ (round to at least three decimal places.)

According to a random sample taken at 12 A.M., body temperatures of healthy adults have a bell-shaped distribution with a mean of 98.2198.21degrees°F and a standard deviation of 0.620.62degrees°F. Using Chebyshev's theorem, what do we know about the percentage of healthy adults with body temperatures that are within 22 standard deviations of the mean? What are the minimum and maximum possible body temperatures that are within 22 standard deviations of the mean?
An automobile assembly line operation has a scheduled mean completion time, μ , of 15 minutes. The standard deviation of completion times is 1.4 minutes. It is claimed that, under new management, the mean completion time has decreased. To test this claim, a random sample of 60 completion times under new management was taken. The sample had a mean of 14.9 minutes. Can we support, at the 0.1 level of significance, the claim that the mean completion time has decreased under new management? Assume that the standard deviation of completion times has not changed. Perform a one-tailed test. Then fill in the table below. Carry your intermediate computations to at least three decimal places, and round your responses as specified in the table.

A local hardware store claims that the mean waiting time in line is less than 3.5 minutes. A random sample of 20 customers has a mean of 3.2 minutes with a standard deviation 0.8 minute.

A fast-food franchise, looking to reduce wait times for customers, launched a pilot program where customers could use a smartphone app to place orders. The mean wait times (in seconds) for in-store and drive-through customers at 10 stores participating in the pilot program and at 10 stores not in the program are recorded. Assume that the population standard deviation of mean wait times is 30 seconds for both groups of stores and that the mean wait times are normally distributed for both groups of stores. Let the mean wait times of the stores not in the program be the first sample, and let the mean wait times of the stores in the program be the second sample. The franchise conducts a two-mean hypothesis test at the 0.05 level of significance, to test if there is evidence that the smartphone app reduces wait times.
