Question
Body temperatures 10 are known to be normally distributed. A medical researcher wants to determine how a g changes the body's temperature. Seven test subjects are randomly selected and the body temperature is measured in degrees Fahrenheit. The subjects are then given the drug and, after 20 minutes, the drug body temperature of each is measured again. The results are given below. From this information the following were determined: x = 99.26 y = 98.7 d = 0.829 s _x = 1.370 s _y = 0.645 s _d = 1.154 Carry out an appropriate hypothesis test to determine if, at alpha = 0.05, there is enough evidence to conclude that the drug changes the body's temperature. Assume that there are no outliers.Explanation / Answer
Below are the null and alternate hypothesis
As p-value is greater than the significance level of 0.05, we fail to reject the null hypothesis.
This means there are not sufficient evidence to conclude that there is significance difference in the body temperature before and after taking the drug.
Null Hypothesis Alternate Hypothesis H0: 1 - 2 = 0 Ha: 1 - 2 <> 0
