how can I use the eight-step hypothesis-testing process for this question?

A sample of 87 professional working women showed that the average amount paid annually into a private pension fund per person was $3352. The population standard deviation is $1100. A sample of 76 professional working men showed that the average amount paid annually into a private pension fund per person was $5727, with a population standard deviation of $1700. A women’s activist group wants to “prove” that women do not pay as much per year as men into private pension funds. If they use and these sample data, will they be able to reject a null hypothesis that women annually pay the same as or more than men into private pension funds? Use the eight-step hypothesis-testing process.

Statistics Problem with Expectation

4. A group of n people are comparing their birthdays. Assume that their birthdays are independent of each other. For simplicity, assume that a year has 360 days (rather than 365 or 366). For (a), assume that these 360 days are all equally likely as birthdays.​(a) Let X be the number of sets of three different people such that the three people in the set share the same birthday as each other. Find E(X).
