Question: Consider the following hypothesis test: H0: 75 HA: < 75 A random sample of 100 observations yields a sample mean of 80.

Consider the following hypothesis test:

H0: µ ≥ 75

HA: µ < 75

A random sample of 100 observations yields a sample mean of 80. The population standard deviation is 30. Calculate the p-value. What is the conclusion to the test if α = 0.10?
