Hi I would like to check the answer and formulas for the following

9.You decide to further your research project by hypothesizing that thetrue average core body temperatureamidst higher ambient temperature and humidity levels for thepopulation who do not use electric fans isgreater thanthose who do use electric fans, setting thelevel of significance at 5%for the formal hypothesis test. In other words, you extend your sampling to two samples instead of just one. You randomly sample 16 and 21 participants

Per Step 5 of the 5-Steps to Hypothesis Testing, choose the appropriate formal and informal conclusions. Assign groups 1 and 2 to be no fans and fans, respectively.

Select one:

a. We do not accept H0 because t = -2.326, where t = -15.885. We do not have statistically significant evidence at = 2.5% to show that the true population average core body temperature amidst higher ambient temperature and humidity levels for those who do not use an electric fan is greater than those who do.

b. We do not reject H1 because t < -1.960, where t = -15.885. We do not have statistically significant evidence at = 10% to show that the true population average core body temperature amidst higher ambient temperature and humidity levels for those who do not use an electric fan is greater than those who do.

c. We do not reject H0 because t < +2.449, where t = -15.885. We do not have statistically significant evidence at = 1% to show that the true population average core body temperature amidst higher ambient temperature and humidity levels for those who do not use an electric fan is greater than those who do.

d. We do not reject H1 because t -1.645, where t = -15.885. We do not have statistically significant evidence at = 5% to show that the true population average core body temperature amidst higher ambient temperature and humidity levels for those who do not use an electric fan is greater than those who do
