Problem 1

A company is testing two versions of a product with a group of people to find out whether they would buy the product. The results are summarized in the table.

product version 1 product version 2 total
would buy it 23 32 55
neutral or would not buy it 12 17 29
total 35 49 84
  1. If each person’s response is only in the table once, how many people reviewed product version 2?
  2. Use a relative frequency table to determine if there is an association between the product versions and whether people would buy each one. Explain your reasoning.

Solution
  1. 49
  2. Sample response:
    product version 1 product version 2
    would buy it 66% 65%
    neutral or would not buy it 34% 35%
    total 100% 100%

    There is no association between the variables. The relative frequencies for each column are very similar and do not indicate that one version is more likely to be purchased than the other.
