Consider the following hypothesis test.

H0: μ1 − μ2 = 0

Ha: μ1 − μ2 ≠ 0

The following results are from independent samples taken from two populations.

Sample 1 Sample 2

n1 = 35

n2 = 40

x1 = 13.6

x2 = 10.1

s1 = 5.9

s2 = 8.5

(a)

What is the value of the test statistic? (Use

x1 − x2.

Round your answer to three decimal places.)

(b)

What is the degrees of freedom for the t distribution? (Round your answer down to the nearest integer.)

(c)

What is the p-value? (Round your answer to four decimal places.)
