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.

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 A new, safe method of memory enhancement became available for purchase.
O Professors required each student to buy 10 notebooks, regardless of the price.
O As the price of textbooks increased, more and more students turned to the used-book market or chose not to buy textbooks at all,
instead using the copies on reserve in the library.
O The quality and design of calculators improved dramatically from 2017 to 2019. For example, calculators made in 2019 accept memory
cards, whereas those made in 2017 do not, but this quality change is hard to measure.
