Question

use the date form the second picture to answer question 3

please help me with question 3

The H3N2 human influenza virus is type of virus abundant in the seasonal flu. The data used in this question comes from a study performed here at CSU in the Department of Biomedical Sciences.
In this study, 16 ferrets were randomly assigned to either receive a vaccine (treatment) or not (control). The weights and temperatures of these ferrets were measured repeatedly for 27 days, and then both groups were exposed to the
H3N2 virus, and their temperatures were measured for a further 5 days. These post exposure days are referred to as the challenge phase of the study.
One symptom of H3N2 infection is increased body temperature. An effective vaccine should mitigate this symptom. The variables in this data set are:
Vaccine: Which group the ferret was assigned to; None
is control, Vaccine is treatment
Max_Temp_Challenge: Highest temperature measured across the challenge phase
There are 10 versions of this data set on Canvas. Your version is 8.
Round all answers to 4 decimal places. You have 5 attempts per question.
1.
a. Using JMP, obtain the mean and standard deviation for Max_Temp_Challenge:
b. Report the 95% CI for population mean Max_Temp_Challenge that JMP calculated:
Lower 95% CI bound:
Upper 95% CI bound:
c. Create an "approximate" 95% CI for population mean Max_Temp_Challenge by hand, using the mean and standard deviation you reported in la. As a reminder, an approximate 95% CI uses a critical value of 2.
Lower 95% CI bound:
Upper 95% CI bound:
2. Have JMP compute confidence intervals for mean of Max_Temp_Challenge for the vaccinated and unvaccinated ferrets separately.
95% CI for vaccinated ferrets:

3. Comparing the 95% Cls for unvaccinated vs. vaccinated ferrets is useful, but what we really should do is create a 95% CI for the difference in population mean Max_Temp_Challenge.
Use "Fit Y by X" to create this confidence interval. Consult the module 5 course notes if you have trouble.
