Question

A random sample of n = 25 is obtained from a population with variance ?2, and the
sample mean is computed to be x= 70. Consider the null hypothesis ?0: m =
80 versus the alternative hypothesis ?1: m < 80.
Compute the p-value when the population variance is o2 = 600.

2. A random sample of n = 25 is obtained from a population with variance o², and the
sample mean is computed to be ĩ = 70. Consider the null hypothesis Ho: µ =
80 versus the alternative hypothesis H1: µ < 80.
Compute the p-value when the population variance is o² = 600.
