There is a claim that the average price of homes in the region is #300,000. Does the data set support of disprove the claim?

  1. A one-sample, left-tail T-test

Is the mean price less than $300,000?

  1. A one-sample, right-tail T-test

Is there any evidence that the mean price is above $300,000?

Exercise 2 - A two-sample T-test

Does the sales price depend on the presence of a pool?

Exercise 3 - A two-sample F-test of variances

How does the variance of sales prices with presence of a pool relate with the variance of sales prices without presence of a pool

Exercise 4 - Parallel boxplots

Visualize the boxplots of the two samples using parallel boxplots.
