For many years, 40% of her clients were in the market for rentals. Lately, she noticed that the proportion of her clients looking to rent seemed to be increasing. Sara decided to use a hypothesis test to see if the population proportion had increased. She took a random sample of 155 of her clients, and found that 50.97% of the sample were in the market for rentals. Perform a hypothesis test at the a - 0.01 significance level to determine whether the population proportion of Sara's clients who are looking to rent has increased. What is the sample proportion of Sara's clients who are looking to rent? O 0.40 O 0.3288 O 0.5097 O 50.97 D Question 40 1 ptsDo not reject Ho . HA is unsupported. O Reject Ho. Accept HA. O Reject Ho.
