Please answer #3 and the subparts, thank you

Step 1

3.1 According to the provided data, the gender gap is provided as mean of man – mean of women. It indicates that all the estimates are statistically significant at 5% level of significance. It can be concluded that estimates are statistically significant and gender gap is large.

Step 2

3.2 The null and alternative hypotheses are:

Null hypothesis: The estimated gender gap is equal to zero.

Alternative hypothesis: The estimated gender gap is larger than zero.

The test statistic can be obtained as:

Step 3

The degrees of freedom = 1594+1368+1838+1871-2 = 6669.

Using the t-distribution table, the t-critical value is obtained as 1.645 which is greater than the calculated test statistic. The null hypothe...
