Question: The null and alternate hypotheses are: H 0 : 1 2 H 1 : 1 > 2 A random sample of 27 items from the

The null and alternate hypotheses are:

H₀: ₁ ₂

H₁: ₁ > ₂

A random sample of 27 items from the first population showed a mean of 114 and a standard deviation of 15. A sample of 15 items for the second population showed a mean of 106 and a standard deviation of 9. Use the 0.025 significant level.
