Chapter 9.1, Problem 9E

To determine

Explain whether the stated hypotheses is correct or not.

Answer to Problem 9E

The hypotheses states in the problem is correct.

Explanation of Solution

Given Information:

Null hypotheses $H_0:\overline{x}=1000$

Alternative hypotheses $H_a:\overline{x}<1000$

By the null hypotheses,population mean value is equal to the 1000.

Thus, $H_0:\overline{x}=1000$ .

By the alternative hypotheses, population mean value is less than 1000.

Thus, $H_a:\overline{x}<1000$ .

Since the null hypotheses, population mean value is equal to the 1000 and the alternative hypotheses population mean value is less than 1000.

Hence, the hypotheses states in the problem is correct.
