Question
You wish to test the following claim (Ha) at a significance level of α=0.01
Ho:μ=52.1
Ha:μ≠52.1
You believe the population is
60.2 | 38.4 | 22.4 | 81.7 | 78.1 |
42.7 | 32.9 | 50.9 | 76.2 | 48.9 |
84.8 | 70.7 | 57.8 | 46.5 | 72.9 |
35.5 | 68.2 | 83.2 | 22.4 | 86.8 |
39.7 | 65.3 | 51.3 | 63.2 | 54.6 |
38.4 | 47.5 | 44.4 | 70.7 | 89.2 |
62.2 | 11.8 | 51.8 | 79.2 | 37.7 |
16.8 | 76.2 | 72.9 | 47.5 | 33.8 |
92.4 | 16.8 | 67.6 | 71.4 | 53.2 |
What is the test statistic for this sample? (Report answer accurate to three 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) 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 52.1.
- There is not sufficient evidence to warrant rejection of the claim that the population mean is not equal to 52.1.
- The sample data support the claim that the population mean is not equal to 52.1.
- There is not sufficient sample evidence to support the claim that the population mean is not equal to 52.1.
