Question 28 Not yet answered Points out of 3.34 P Flag question Time left 0:30:58 Hide A 2010 study asserts that the number of hours that the average college student studies each week has been steadily dropping (The Boston Globe, July 4, 2010). In fact, the researchers state that, in the U.S., today's undergraduates study an average of 14 hours per week. Suppose an administrator at a local university wants to show that the average study time of students at his university differs from the national average. He takes a random sample of 35 students at is university and finds that the average number of hours spent studying per week is 16.9. Assume that the population standard deviation is 7.2 hours. At 0.05 level of significance, what is the test statistics for testing the hypotheses H0: $\mu$ = 14 versus H1: $\mu$ $\neq$ 14? Select one: 2.38 1.89 1.96 2.22

From the experiment in Part 2 we see that when the force is kept constant, a) the more massive the elephant, the easier it will be to move. b) the mass of the elephant does not affect how hard or easy it is to get it to move. c) the more massive the elephant, the harder it will be to move. d) the mass of the elephant can affect how hard or easy it is to get it to move, but sometimes increasing the mass makes it easier to move, sometimes it makes it harder. There is no clear relation as such.

b. Consider the scenario. The country Global-Land is really small and only has 500 inhabitants. In 2023 in total, they spend ECD 200,000 per year on food, ECD 200,000 on clothing, and ECD 100,000 on public and private transport. The economy of Global-Land has three industries: Juice, Clothing and Furniture. The output of each industry is disposed either on the domestic market or exported. The institutional sectors of the economy are the Household, Government, Corporate and Rest of the World, which either purchase the products of the industries or provide the factor services. The Juice and Clothing industries just bought ECD 2,000,000 worth of new machinery. Meanwhile, the Furniture is the largest industry. This industry has increased its inventory by ECD 200,000 as compared to the previous year. In addition to that, a Global-Land resident buys a new house worth ECD 300,000. Of course, the government of Global-Land knows how important education is. Therefore, it spends ECD 1,000,000 a year to run a public school and pay all the teachers who work there. In addition to that, the government contributes ECD 500,000 to fix broken roads and highways throughout the year. In addition, Global-Land total domestically produced goods and services is worth ECD 1,500,000 this year. In the meantime, the country also purchase foreign goods and services is worth ECD 1,000,000. i. Using the information provided in the scenario, calculate GDP using the expenditure approach. Please show all components of each measure. (20 marks) 4 marks for calculating GDP and 4 marks each for calculating each section of the expenditure approach.
