6 . Calculating inflation using a simple price index Consider a fictional price index, the College Student Price Index (CSPI), based on a typical college student's annual purchases. Suppose the following table shows information on the market basket for the CSPI and the prices of each of the goods in 2017, 2018, and 2019. The cost of each item in the basket and the total cost of the basket are shown for 2017. Perform these same calculations for 2018 and 2019, and enter the results in the following table. 2017 2018 2019 Price Cost Price Cost Price Cast Quantity in Basket (Dollars) (Dollars) (Dollars) (Dollars) (Dollars) (Dollars) Notebooks 15 2 3.0 Calculators 1 70 70 100 130 Large coffees 250 2 500 2 2 Energy drinks 50 100 Textbooks 10 120 1,200 150 180 Total cost 1,900 Price index 100 Suppose the base year for this price index is 2017. In the last row of the table, calculate and enter the value of the CSPI for the remaining years. Between 2017 and 2018, the CSP1 increased by| - Between 2018 and 2019, the CSPI increased by | Which of the following, if true, would illustrate why price indexes such as the CSPI might overstate inflation in the cost of going to college? Check all that apply. O Professors required each student to buy 10 textbooks, regardless of the price. O As the price of calculators rose, fewer students decided to buy them, opting instead to use the free calculators in their cell phones or on their computers. D A new mobile device for personal computing became available for purchase. O Energy drinks became increasingly popular on college campuses between 2017 and 2019 due to significant improvements in flavor, but this quality change is hard to measure
