Question

A simple random sample of the sitting heights of 36 male students has a mean of 92.8cm. The population of males has sitting heights with a mean of 91.4 cm and a standard deviation of 3.6 cm. Using a 0.05 significance level to test the claim, the p-value of 0.0198 is found. What is the final conclusion about testing the claim that male students have a sitting height different from 91.4 cm. Could anyone show me how to do this?

Answer 1

there is sufficient evidence to support the claim that male student have a sitting height different of 91.4 cm.

Explanation:

p value = 0.0198

level of significance = 0.05

hypothesis:-

`H_(0):\mu=91.4`

`H_(1):\mu\\eq91.4`

decision:-

p value = 0.0198 <0.05

so, we reject the null hypothesis.]
