Manually construct a 95% confidence interval for the change in the gender gap in average hourly earnings between 1992 and 2008. (hint portion in the second image attached) 3. Based on the analysis answer the following questions: 1. Is the gender gap large? Why? 2. Did the estimated gender gap increased from 1992 to 2008? If so, how much? Is this increase statistically significant at the 5% level? 3. How large is the gender gap in 1992 and 2008 if it is measure in percentage terms? Do you think it is large?

Permutations and Combinations

If there are 5 dishes, they can be relished in any order at a time. In permutation, it should be in a particular order. In combination, the order does not matter. Take 3 letters a, b, and c. The possible ways of pairing any two letters are ab, bc, ac, ba, cb and ca. It is in a particular order. So, this can be called the permutation of a, b, and c. But if the order does not matter then ab is the same as ba. Similarly, bc is the same as cb and ac is the same as ca. Here the list has ab, bc, and ac alone. This can be called the combination of a, b, and c.

Counting Theory

The fundamental counting principle is a rule that is used to count the total number of possible outcomes in a given situation.
