1. Work through a t-test to compare the means of two groups of data.

2. Work through a chi-square test to compare the expected and observed frequencies of two groups.

There are three hypothesis tests here. Two for question 1 and one for question 2. For each write down 1) the null and alternative hypotheses, 2) the significance level, 3) your calculated the test statistic, 4) the critical value for the significance level, and 5) your conclusion! I WANT TO SEE THESE NUMBERED!

To keep things simple, restrict yourselves to first 30 rows of data, also let's use intrinsic and extrinsic columns for question 1 and gender column for question 2
