You may need to use the appropriate appendix table or technology to answer this question. Consider the following hypothesis test.

H₀: _{1 2} 0

H_a: _{1 2} > 0

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

Sample 1	Sample 2
n1 = 40	n2 = 50
x1 = 25.9	x2 = 22.8
1 = 5.7	2 = 6

(a)What is the value of the test statistic? (Round your answer to two decimal places.)

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

(c)With = 0.05, what is your hypothesis testing conclusion?

a. Do not reject H₀. There is insufficient evidence to conclude that _{1 2} > 0.

b. Do not Reject H₀. There is sufficient evidence to conclude that _{1 2} > 0.

c. Reject H₀. There is insufficient evidence to conclude that _{1 2} > 0.

d. Reject H₀. There is sufficient evidence to conclude that _{1 2} > 0.
