I am in statistics and having major trouble finding out how to do this. I have looked everywhere - my textbook firstly which contains no info on this. I had the math program walk me through it but it skips over HOW to do it of course. I have googled like crazy. Someone please help!!

The problem is as follows:

A study was done using a treatment group and a placebo group. The results are shown in the table. Assume that the two samples are independent simple random samples selected from the normally distributed populations, and do not assume that the population standard deviations are equal. Complete parts a and b. The picture I am attaching does not show part b cause I had not answered part a yet. I know what part a is.. the answer is c but I need help with finding the p-value. Part b asks for the p-value. Thanks in advance for any help!
