How many Kleenex should the Kimberly Clark Corporation package of tissues contain? Researchers believed that 60 is the average number of tissues used during a cold. They collected a random sample of 100 Kleenex users. The sample yielded a mean of 52 and standard deviation of 22 on the number of tissues used during a cold. 3) Note that the standard deviation is estimated from the current sample rather than provided upfront. In a hypothesis test for determining whether the average number of tissues used during a cold is 60, What distribution does the test statistic follow? (Hint: The test statistic is called a t. The name of this hypothesis test is called the one-sample t-test. The shape of at- distribution is very close to a normal distribution. In fact, we should say that the normal distribution is a special case of the -distribution with a infinitely large sample.)
