Answer:
Null hypothesis:
B) H0: μ1 = μ2 = μ3 = μ4
Alternate hypothesis:
A) H1: At least one mean is different.
Reject H0 if F>2.74
H0 is rejected
Step-by-step explanation:
Null hypothesis always contain equality so, null hypothesis would be
B) H0: μ1 = μ2 = μ3 = μ4.
Alternate hypothesis doesn't contain equality so, alternate hypothesis would be
A) H1: At least one mean is different.
Decision rule will be "reject null hypothesis if calculated F is greater than critical value of F".
Critical value of F is F0.05(3,68)=2.74.
So, decision rule will be Reject H0 if F>2.74.
As, calculated F 2.77 is greater than 2.74 so, we reject our null hypothesis and conclude that there is sufficient evidence to suggests a difference in the means for the different types of mail at 5% level of significance.

Answer:
$338.50
Step-by-step explanation:
Simple interest would be i = ($2500)(0.09)(1.5 yrs) = $338.50
