We want to describe and examine the relationship between the apartment's number of days in the market and its year built.

Use the two-way frequency table above to answer the following questions.

To assess whether there is a relationship the number of days the apartments were in the market and its year of build in the population, we conduct an appropriate hypothesis test. You must show all the steps of the hypothesis test.

	Year built	Number of days in market
30 days or less	Over 30 days	total
	Before 2010	10	6	16
Between 2010 and 2016	20	20	40
between 2017 and 2021	30	34	64
	total	60	50	120
