A problem with a telephone line that prevents a customer from receiving or making calls is upsetting to both the customer and the telephone company. Samples of 20 problems reported to two different offices of a telephone company and the time to clear these problems(in minutes) from thecustomers' lines are provided. Complete(a) through(d) below.

The following is a sample of 20 problems reported to the first office and the time(in minutes) to clear those problems.

1.64, 1.56, 0.71, 2.76, 0.46, 1.90, 4.04, 3.88, 1.71, 3.08, 1.25, 0.58, 0.94, 1.65, 0.86, 1.21, 6.04, 3.98, 5.57, 0.98

The following is a sample of 20 problems reported to the second office and the time(in minutes) to clear those problems.

7.39, 3.55, 0.08, 1.10, 0.45, 0.33, 0.32, 2.09, 0.31, 4.02, 3.65, 0.94, 1.94, 0.26, 1.60, 4.05, 0.06, 1.50, 1.56, 0.98

Assuming that the population variances from both offices areequal, is there evidence of a difference in the mean waiting times between the twooffices? equals=0.05

Let 1 be the mean waiting time of the first office and 2 be the mean waiting time of the second office. Determine the hypotheses. Choose the correct answer below.

A: H0: u1=u2 & H1: u1 does not = u2

B: H0 : u1 does not + u2 & H1 : u1 = u2

C: H0 : u1 larger than or equal to u2 & H1: u1 < u2

D: H0: u1 smaller than or equal to u2 & H1: u1>u2

Determine the test statistic.

tStat= __

Determine the criticalvalue(s) __

Choose the correct conclusion below.

A Reject H0. There is sufficient evidence that the means differ.

B Do not reject H0. There is sufficient evidence that the means differ.

C Do not reject H0. There is insufficient evidence that the means differ.

Find thep-value in(a) and interpret its meaning

P-Value = __
