You wish to test the following claim (HaHa) at a significance
level of α=0.001α=0.001.
Ho:μ=72.8Ho:μ=72.8
Ha:μ>72.8Ha:μ>72.8
You believe the population is normally distributed, but you do
not know the standard deviation.
- What is the test statistic for this sample?
test statistic = Round to 3 decimal places
- What is the p-value for this sample?
p-value = Round to 4 decimal places.
- The p-value is...
- less than (or equal to) αα
- greater than αα
- 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 72.8.
- There is not sufficient evidence to warrant rejection of the
claim that the population mean is greater than 72.8.
- The sample data support the claim that the population mean is
greater than 72.8.
- There is not sufficient sample evidence to support the claim
that the population mean is greater than 72.8.
