QuestionDetermine the parameter to be tested, and the test to be performed.
Part: 0 / 6 $\square$
Part 1 of 6
A simple random sample of size 65 has mean $\bar{x}=7.26$ and the standard deviation is $s=1.9$ . Can you conclude that the population mean is greater than 9 ? Determine the parameter to be tested.
The parameter to be tested is the population (Choose one) $\square$

Studdy Solution

STEP 1

1. We have a simple random sample of size $n = 65$ .
2. The sample mean is $\bar{x} = 7.26$ .
3. The sample standard deviation is $s = 1.9$ .
4. We are testing if the population mean is greater than 9.

STEP 2

1. Identify the parameter to be tested.
2. Determine the appropriate hypothesis test.

STEP 3

Identify the parameter to be tested. In this context, we are interested in the population mean.
The parameter to be tested is the population mean, denoted as $\mu$ .
The parameter to be tested is the population mean.
