A survey organization conducted 800 telephone interviews in 2019 and 813 telephone interviews in 2024 in which randomly selected adults in the United States were asked if they think Twitter (technically X.com, but everyone remembers it as Twitter) is an effective way to promote a new product. A 98% confidence interval for the difference in the proportion (p2024 - p2019) that believe Twitter is an effective way to promote a new product is (-0.105,-0.01). (a) What can we conclude from the confidence interval? There IS evidence that the proportion of people that feel Twitter is an effective way to promote a new product remained the SAME from 2019 to 2024.There IS NOT enough evidence that the proportion of people that feel Twitter is an effective way to promote a new product CHANGED from 2019 to 2024. There IS evidence that the proportion of people that feel Twitter is an effective way to promote a new product INCREASED significantly from 2019 to 2024.There IS evidence that the proportion of people that feel Twitter is an effective way to promote a new product DECREASED significantly from 2019 to 2024. (b) If researchers want to use the confidence interval to determine if there is a difference in the proportion that believe Twitter is an effective way to promote a new product, what can we definitely conclude about the p-value? Based on the interval provided, select true if the statement is certainly true, select false if it is certainly false, or select "can't know" if we would need more information to conclude whether it's true or false. i) The p-value is less than 0.1. ---Select--- True False Can't know ii) The p-value is less than 0.02. ---Select--- True False Can't know

Analytical Question 3 (15 marks) Suppose that the nominal exchange rate e between the Canadian and American dollar is 1.3 ($1 USD = $1.3 CAD). Also suppose that the average annual cost of living of a family of four in Toronto (Canada) is $65000 CAD and in New York (USA) it is $55000 USD. (a) Calculate Canada's real exchange rate e. [Hint: Canada is the domestic country and USA is the foreign country. Price level in this question is the cost of living.] (b) Suppose you have been offered a job by an international firm that has offices in both Toronto and New York. You can choose whichever of the two cities you prefer. Your salary will be $80000 USD regardless of your choice of city. You equally like both cities so the decision will depend entirely on the cost of living considerations. Which city will you choose and why? (c) Is the Canadian dollar overvalued or undervalued? Based on the cost of living numbers, what is the fair nominal exchange rate? [Hint: use the idea of Purchasing Power Parity to find out the fair nominal exchange rate between CAD and USD.]
