Question
You wish to test the following claim (HaHa) at a significance level of α=0.002
Ho:μ=72.6
Ha:μ<72.6
You believe the population isnormally distributed , but you do not know the standard deviation. You obtain the following sample of data:
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...
This test statistic leads to a decision to...
As such, the final conclusion is that...
Ho:μ=72.6
Ha:μ<72.6
You believe the population is
94.7 | 57.9 | 57 | 55.3 | 48.5 |
81.5 | 46.2 | 61.7 | 76.9 | 75.5 |
63.9 | 49.2 | 82.9 | 62.1 | 50.5 |
72.9 | 52.3 | 57.4 | 63.2 | 80.2 |
82.2 | 71.6 | 75 | 69 | 57 |
62.5 | 52.8 | 50.5 | 61.4 | 82.2 |
58.7 | 62.8 | 75.5 | 49.2 | 55.7 |
87.6 | 72.4 | 56.2 | 48.5 | 90.4 |
79.6 | 32.1 | 69 | 76.9 | 47.8 |
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 less than 72.6. - There is not sufficient evidence to warrant rejection of the claim that the population mean is less than 72.6.
- The sample data support the claim that the population mean is less than 72.6.
- There is not sufficient sample evidence to support the claim that the population mean is less than 72.6.
