Question: The null and alternate hypotheses are: H 0 : 1 2 H 1 : 1 > 2 A random sample of 20 items from the

The null and alternate hypotheses are:

H₀:₁₂

H₁:₁>₂

A random sample of 20 items from the first population showed a mean of 100 and a standard deviation of 15. A sample of 16 items for the second population showed a mean of 94 and a standard deviation of 8. Use the .05 significant level.

a.	Find the degrees of freedom for unequal variance test.(Round down your answer to the nearest whole number.)

Degrees of freedom

b.	State the decision rule for .05 significance level.(Round your answer to 3 decimal places.)
