Question 14: A landlord of an apartment complex bases the company's advertising on the proportion of available units in different sizes. In the past, the proportions were: 12% studios, 10% 1-Bedroom, 21% 2- Bedroom, and 57% 3-Bedroom. To confirm if these numbers were still accurate, a count of available units was conducted with the following results: 18 studios, 56 1-Bedroom, 10 2-Bedroom, and 30 3- Bedroom. Test at a 0.05 level of significance if the previous proportions are still valid. Part A: State the null and alternate hypotheses. Part B: List the values of the expected counts. Part C: Determine the test statistic. Part D: Determine the p-value. Part E: Draw a conclusion.
