Question

The mean weight of female aerobics instructors in a certain city is less than 136 lbs. Express the null and alternative hypotheses in symbolic form for this claim.

Answer 1

Explanation:

We are given the claim.

Claim: The mean weight of male aerobics instructors in a certain city is more than 182 lbs.

Population mean = 182 lbs

The null hypothesis will state that the sample mean is less than or equal to the population mean 182 lbs.

The alternate hypothesis will state that mean weight of male aerobics instructors in a certain city is more than 182 lbs.

Answer 2

H0 : μ ≤ 186

H1 : μ > 186

Explanation:

The null hypothesis and hypothesis differ in that the null aligns with the claim or value of the population parameter. The alternative hypothesis tries to negate the null hypothesis by trying to displace the claim set by the parameter based on the average or mean value of the sample.

Since the claim Given by the population mean is that mean weight is less Than 186 ; then this will be the null hypothesis and an opposite statement will be declared as the alternative.
