You wish to test the following claim (H1) at a significance level of =0.001
Ho:=88.7
H1:>88.7
You believe the population is normally distributed, but you do not know the standard deviation. You obtain a sample of sizen=799with meanx=89.7 and a standard deviation ofs=7.2
.
What is the test statistic for this sample? (Report answer accurate to two 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 greater than 88.7.
- There is not sufficient evidence to warrant rejection of the claim that the population mean is greater than 88.7.
- The sample data support the claim that the population mean is greater than 88.7.
- There is not sufficient sample evidence to support the claim that the population mean is greater than 88.7.
