To express the null and alternative hypotheses for the claim that the mean weight of male nurses working at a local hospital is equal to 183 lbs, we can use the following symbolic forms:
- Null hypothesis (H0): \( \mu = 183 \)
- Alternative hypothesis (H1): \( \mu \neq 183 \)
In terms of the provided codes, it can be written as:
- H0: mu = 183 (as is)
- H1: mu != 183
So the final result would be:
H0: mu = 183
H1: mu != 183
