Question

The mean salary for a new teacher in your town is $48,000. You believe it is higher for new teachers in a neighboring town. State the null and alternative hypotheses.

Answer 1

Explanation:

Given that the mean salary for a new teacher in your town is $48,000

You believe it is higher for new teachers in a neighboring town.

So to prove or disprove your claim you have to show statistical evidence.

For that hypothesis testing is necessary.

You must conduct a hypothesis test for comparing the mean of salary of new teacher with neighbouring places

The hypotheses wouldbe

`H_0: \mu = 48000\\H_1: \mu >48000`

where mu is the average for neighbouring states.
