hypothesis testing help

Resolved Question:
Can someone please explain the following question?

Assume that you have a sample of n1 = 8, with the sample mean x1 = 42, and a sample standard deviation s1 = 4, and you have an independent sample of n2 = 15 from another population with a sample mean of x2 = 34 and a sample standard deviation S2 = 5.

1.What is the value of the pooled-variance tstat test statistic for testing Ho: µl = µ2?

1.In finding the critical value ta/2, how many degrees of freedom are there?

1.Using the level of significance a = 0.01, what is the critical value for a one-tail test of the hypothesis Ho: µl ≤ µ2 against the alternative, H1: µ1 > µ2?

1.What is your statistical decision?

Hi;

For 1), what is the significance level?
