(1 point) Office occupancy In a city is an indication of the economic health of the region in which it is located. Suppose a random sample of offices in Boston and Chicago was selected and the number of vacancies was recorded. Round all answers to four decimal places City Vacant Not Vicent Total Boston 26 108 194 Chicago 18 138 156 Total 44 306 350 Our research question is, is there a difference in the vacancy rates for these two cities?" 1. What are the hypotheses for testing whether there is a difference? Ho: The variables City and Vacancy are independent The difference in the vacancy rates in the sample data is due to chance H,: The variables are not independent. The difference in the vacancy rate is not due to chance 2. Calculate the difference in vacancy rates for these two cities: Prome Poncare 3. The paragraph below describes the setup for a randomization test We write Boston on cards and Chicago on cards. Then we shuffle the cards and split them into two groups on representing occupied offices representing vacant offices and one group of size group of size We calculate the proportion of Boston offices that are vacant and subtract the proportion of Chicago offices that are Vacant to get PChicap,in and build a histogram of this simulated differences.

Cheryl takes a different sample and conducts the hypothesis test. She gets a p-value of 0.1448. How much widence does Chery have that the ne model is not a good fit for her observed result?
