Question
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 2014, 2015, and 2016.
The cost of each item in the basket and the total cost of the basket are shown for 2014.
Perform these same calculations for 2015 and 2016, and enter the results in the following table.

Explanation:
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.
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.
The quality and design of calculators improved dramatically from 2014 to 2016. For example, calculators made in 2016 accept memory cards, whereas those made in 2014 do not, but this quality change is hard to measure.
Professors required each student to buy 10 textbooks, regardless of the price.
A new, safe method of memory enhancement became available for purchase.

The cost is calculated by multiplying the price of the concerned year with the quantity. The CSPI has been calculated by dividing the total cost of current year with that of the base year.
Between 2014 and 2015, the CSPI increased by 20% (120-100)/100 = 20
Between 2015 and 2016, the CSPI increased by 25% (150-120)*100/120 = 25
