This is a homework question I was assigned and I am completely lost. I need to know what are the key numbers I should be looking at and need to use, and what is the formula for finding the p-value? Any help at all would be amazing since I am lost.
Cheers,

A sample of 65 observations is selected from one population. The sample mean is 2.67 and the sample standard deviation is 0.75. A sample of 50 observations is selected from a second population. The sample mean is 2.59 and the sample standard deviation is 0.66. Conduct the following test of hypothesis using a 0.08 significance level.
Ho: µ1 < µ2
H1: µ1> µ2
1. Is this a one-tailed or two-tailed test?
2. State the decision rule.
3. Compute the value of the test statistic.
4. What is your decision regarding Ho?
5. What is the p-value?
