Question 12 (1 point)
Assume you have a t-test for the difference between two means:
H_(0):mu _(1)-mu _(2)=0
H_(A):mu _(1)-mu _(2)!=0
From a survey, you know that /bar (y)_(1)=101(,)/(b)ar (y)_(2)=83, and SE(/bar (y)_(1)(-)/(b)ar (y)_(2))= 2.3. After calculating the degree of freedom, you use software to find the corresponding critical value for a 95% confidence interval to be 2.4 . Construct the 95% confidence interval for the mean and report the upper limit.
Note:
1- Only round your final answer to the nearest integer.
