pestation period is 16 days. Suppose you have a sample of 27 Syrian hamsters who were exposed to high levels of the hormone progesterone when they were pups, and who have an average gestation length of 17.4 days and a sample variance of 33.7 days. You want to test the hypothesis that Syrian hamsters who were exposed to high levels of the hormone progesterone when they were pups have a different gestation length than all Syrian hamsters.

Gestation period is the length of pregnancy, or to be more precise, the interval between fertilization and birth. In Syrian hamsters, the average
gestation period is 16 days.

What is the probability of
getting the t statistic or something more extreme for the sample size of n = 95? p =
The t distribution is
with a larger n. (Hint: To best see this, click the radio button in the tool with no vertical lines.
Slowly move the Degrees of Freedom slider from the smallest value to the largest value, and observe how the shape of the distribution changes.)
