How to find the P-value?
A large software company gives job applicants a test of programming ability, and the mean for
the test has been 160 in the past. Twenty-five applicants are randomly selected from one large
university and they produce a mean score of 165, with a standard deviation of 13. At a significance
level of 0.05, does this indicate that the sample comes from a population with a mean score greater
than 160?
I only want to know what kind of test i should use for this question.

Since the sample standard deviation is given, this problem involves a one-sample t-test.
