You wish to test the following claim (HaHa) at a significance level of α=0.005α=0.005.
Ho:μ=60.4Ho:μ=60.4
Ha:μ≠60.4Ha:μ≠60.4
You believe the population is normally distributed, but you do not know the standard deviation. You obtain a sample of size n=5n=5 with mean ¯x=63.4x¯=63.4 and a standard deviation of s=7.5s=7.5.
- 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 not equal to 60.4.
- There is not sufficient evidence to warrant rejection of the claim that the population mean is not equal to 60.4.
- The sample data support the claim that the population mean is not equal to 60.4.
- There is not sufficient sample evidence to support the claim that the population mean is not equal to 60.4.
