Researchers claim that 60 tissues is the average number of tissues a person uses during the course of a cold. The company who makes Kleenex brand tissues thinks that the claim is untrue, but is not sure whether the average is greater than or less than 60. What are their null and alternative hypotheses?

H0 : μ = 60 and H1 : μ ≠ 60

Explanation:

H0 : μ = 60 and H1 : μ ≠ 60

Where;

H0 = the null hypothesis

μ = mean value

H1 = alternative hypothesis

The null hypothesis is our initial assumption, which is the claim that the average number of tissue used during the course of a cold is 60.

The alternative hypothesis will look to negate the null hypothesis, which is to establish that the mean number of tissues used during the course of a cold is not 60, meaning it could be less or more.
