2.) Sort the real estate data into a table that shows the number of homes that have a garage attached versus those that do not have a garage in each of the five townships.If a home is selected at random, compute the following probabilities.

A.) The home has a garage attached.

B.) Given that it is in Township 5, that it does not have a garage attached.

6.) Refer to the wage data, which report information on annual wages for a sample of 100 workers.Also included are variables relating to industry, years of education, and gender for each worker.(Minitab: Graph – Box plot – One y Simple – select variable)
