Researchers claim that 60 tissues is the average number of tissues a person uses during the course of a cold.

Answer:

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.
