Question

You wish to test the following claim (HaHa) at a significance level of =0.02=0.02. Ho:=80.9Ho:=80.9 Ha:<80.9Ha:<80.9 You believe the population is normally distributed, but you do not know the standard deviation. You obtain a sample of size n=74n=74 with mean M=77M=77 and a standard deviation of SD=8.4SD=8.4. What is the test statistic for this sample? (Report answer accurate to three decimal places.) test statistic = What is the p-value for this sample? (Report answer accurate to four decimal places.) p-value = The p-value is...
- less than (or equal to)
- greater than
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 80.9.
- There is not sufficient evidence to warrant rejection of the claim that the population mean is less than 80.9.
- The sample data support the claim that the population mean is less than 80.9.
- There is not sufficient sample evidence to support the claim that the population mean is less than 80.9.
