Examine the following hypotheses:

H₀: mu(ya)=mu(yb)
H_a: mu(ya)<mu(yb)

Examine the SAS output for the data collected to assess these hypotheses and answer the following questions.

1. What can you say about normality for each population.
2. What can you say about consistency.
3. What can you say about the variance for each population.
4. Comment on the significance of the p-value for the hypotheses above.
