Hi i would like to check the following answer and formula.

15 You decide to further your research project by hypothesizing that thetrue proportion of core body temperature increasesamidst higher ambient temperature and humidity levels for thepopulation who do not use electric fans isless thanthose who do use electric fans, setting thelevel of significance at 2.5%for the formal hypothesis test. In other words, you extend your sampling to two samples instead of just one. You randomly sample 50 and 34 participants

Per Step 5 of the 5-Steps to Hypothesis Testing, choose the appropriate formal and informal conclusions.

:

a. We accept H1 because z +1.645, where z = -2.044. We do not have statistically significant evidence at = 1% to show that the true proportion of core body temperature increases amidst higher ambient temperature and humidity levels for the population who do not use electric fans is less than those who do use electric fans.

b. We reject H0 because z -1.960, where z = -2.044. We have statistically significant evidence at = 2.5% to show that the true proportion of core body temperature increases amidst higher ambient temperature and humidity levels for the population who do not use electric fans is less than those who do use electric fans.

c. We accept H1 because z > -2.326, where z = -2.044. We have statistically significant evidence at = 2.5% to show that the true proportion of core body temperature increases amidst higher ambient temperature and humidity levels for the population who do not use electric fans is less than those who do use electric fans.

d. We reject H1 because z -1.645, where z = -2.044. We do not have statistically significant evidence at = 10% to show that the true proportion of core body temperature increases amidst higher ambient temperature and humidity levels for the population who do not use electric fans is less than those who do use electric fans.
