Please help with these homework practice problems, thank you!

Consider the following hypothesis test:

H0: u 1- u 2 = 0

Ha: u 1 - u 2 (equals sign with a line in it) 0

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

Sample 1

n1 = 35

x1 (with a line over it) = 13.6

s1 = 5.3

Sample 2

n2= 40

x2 (with a line over it) = 10.1

s2 = 8.1

a. What is the value of the test statistic (to two decimals)?

b. What is the degrees of freedom for the t distribution? (Round down your answer to the whole number)

thank you in advance!
