You wish to test the following claim (HaHa) at a significancelevel of α=0.001α=0.001.
      Ho:μ=88.9
      Ha:μ>88.9
You believe the population is normally distributed, but you do notknow the standard deviation. You obtain a sample of size n=79 withmean M=91.5 and a standard deviation of SD=16.3
What is the test statistic for this sample? (Report answer accurateto three decimal places.)
test statistic =
What is the p-value for this sample? (Report answer accurate tofour decimal places.)
p-value =
The p-value is... (choose one)
- less than (or equal to) α
- greater than α
This test statistic leads to a decision to...(choose one)
- reject the null
- accept the null
- fail to reject the null
As such, the final conclusion is that...(choose one)
- There is sufficient evidence to warrant rejection of the claimthat the population mean is greater than 88.9.
- There is not sufficient evidence to warrant rejection of theclaim that the population mean is greater than 88.9.
- The sample data support the claim that the population mean isgreater than 88.9.
- There is not sufficient sample evidence to support the claimthat the population mean is greater than 88.9.
