Question

Below, a statistical test is described. Define the relevant parameter(s) in the context of this situation. Testing to see if the average number of hours college student sleep on a weeknight is less than 6.5 hours.

Parameter of interest:
State the null and alternative hypotheses. H o:
H a:

I put 6.5 into all 3 because someone said it might correct and it was not.​

Answer 1

The parameter of interest in this situation is the population mean of the number of hours college students sleep on a weeknight.

The null hypothesis (H0) is that the population mean is equal to or greater than 6.5 hours.

H0: µ ≥ 6.5

The alternative hypothesis (Ha) is that the population mean is less than 6.5 hours.

Ha: µ < 6.5

Note: It's important to understand that the parameter of interest is the population mean, which is unknown, and the null and alternative hypotheses are statements about the population mean. The value of 6.5 is the hypothesized value for the population mean that is being tested.
