Question 7: You wish to test the following claim (HaHa) at a significance level of α=0.10α=0.10.
Ho:μ=82.3Ho:μ=82.3
Ha:μ<82.3Ha:μ<82.3
You believe the population is
What is the critical value for this test? (Report answer accurate to three decimal places.)
critical value =
What is the test statistic for this sample? (Report answer accurate to three decimal places.)
test statistic =
The test statistic is...
- in the critical region
- not in the critical region
This test statistic leads to a decision to...
- reject the null
- accept the null
- fail to reject the null
As such, the final conclusion is that...
- There is sufficient evidence to warrant rejection of the claim that the population mean is less than 82.3.
- There is not sufficient evidence to warrant rejection of the claim that the population mean is less than 82.3.
- The sample data support the claim that the population mean is less than 82.3.
- There is not sufficient sample evidence to support the claim that the population mean is less than 82.3.
