The mean weight of male nurses working at a local hospital is at most 187 lbs. Express the null and alternative hypotheses in symbolic form for this claim.

\[ H_0: \mu \leq 187 \]

\[ H_1: \mu > 187 \]

Answer :

The null and alternative hypotheses in symbolic form for this claim is

H0: μ ≤ 187lbs

H1: μ > 187lbs

Expressing the null and alternative hypotheses

From the question, we have the following parameters that can be used in our computation:

Mean weight = At most 187lbs

The mean weight is at most 187lbs

So, we have the null hypothesis to be

H0: μ ≤ 187lbs

The alternate is the opposite of the null hypothesis

So, we have

H1: μ > 187lbs
