Question
You wish to test the following claim (HaHa) at a significance level of =0.01=0.01. Ho:=88.2Ho:=88.2 Ha: <88.2Ha: <88.2 You believe the population is normally distributed,
You wish to test the following claim (HaHa) at a significance level of =0.01=0.01. Ho:=88.2Ho:=88.2 Ha:<88.2Ha:<88.2 You believe the population is normally distributed, but you do not know the standard deviation. You obtain a sample of size n=60n=60 with mean M=80.9M=80.9 and a standard deviation of SD=20.9SD=20.9. 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 88.2.
- There is not sufficient evidence to warrant rejection of the claim that the population mean is less than 88.2.
- The sample data support the claim that the population mean is less than 88.2.
- There is not sufficient sample evidence to support the claim that the population mean is less than 88.2.
