You are on a research team that is investigating the mean temperature of adult humans. The commonly accepted claim is that the mean temperature is about 98.6 degrees F. You want to show that this claim is false. How would you write the null and alternative hypothesis? Now assume that you have a sample of 35 adults and their mean temperature is 97.8 and the standard deviation of the temperatures is 0.8 Complete the test with alpha = 0.01
1. What is the p-value and why? How did you calculate that?
2. What is the 95% confidence interval based on this sample?
3. Complete the test with critical values and provide the answer ( reject or not)?
4. Complete the test with p-value (reject or not)?
5. Do you reject or not reject the claim, the null or the alternative and why? Is it always like this?
6. What is your conclusion??? Is your conclusion related to the null, the alternative of the claim and why? Is it always like this?
