You wish to test the following claim (HaHa) at a significance level of α=0.001α=0.001.
Ho:μ=64.9Ho:μ=64.9
Ha:μ>64.9Ha:μ>64.9
You obtain a sample of size n=301n=301 with mean ¯x=68.2x¯=68.2 and a standard deviation of s=20.5s=20.5.
- 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 = Use Technology 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 64.9.
- There is not sufficient evidence to warrant rejection of the claim that the population mean is greater than 64.9.
- The sample data support the claim that the population mean is greater than 64.9.
- There is not sufficient sample evidence to support the claim that the population mean is greater than 64.9.
