Question

According to a recent study, the average woman's leg hair grows an eighth of an inch per month. A new drug company believes that women who daily take its drug will change their leg hair growth. Before putting its product on the market, the company plans on running a test of the effectiveness of the drug.
a. Which null and alternative hypotheses should the company use for this study?

Answer 1

Answer:

Step-by-step explanation:

Null hypothesis should be: The average woman's leg hair grows an eighth of an inch per month: u = eighth of an inch

Alternative hypothesis: The average woman's leg hair growth is not an eighth of an inch per month after treatment: u ≠ eighth of an inch

This test after carrying out its treatment will be able to determine if the drug was effective or not
