M4a: Hypothesis Testing Scenario Assignment

Scenario Script

Caption: As you prepared your memo about the new “Princess Select” line, you discovered that the sample

size that you were provided was insufficiently small. Using a larger sample of 200 customers, you conducted

this research and the data is now ready for your analysis.

The following results were found:

1. Sample mean for price was $46.60 with a standard deviation of $5.90

2. Proportion who would purchase the new product was 78%

Mieke: You have the new data already? Great. So, like I said previously, at least 85% of the customers must

express some desire for the product. The customers who are interested in the product must be willing to pay at

least $47.50.

Scenario Assignment

Using this information, complete the following:

1. Conduct hypothesis tests for price and proportion.

2. Based on this updated data and Mieke’s parameters, should the new line be marketed? Explain your answer.
