Paired t-test Execution
For this question use the following values: n = 13,sD = 1.20, andd = -1.01.Compute the upper limit of the 93% confidence interval on the differencebetween population means.
Group of answer choices
-0.955
-0.787
-0.507
-0.434
-0.348
-0.090
0.044
0.103
0.132
0.690
We have here for given example,
Sample mean for difference=-1.01
Sample standard deviation for difference=1.2
Sample size=13
Degree of freedom =n-1=12
Level of significance =0.07
t critical value (by using t table) =1.989
Confidence interval upper limit for paired t test is
=-0.348
Upper limit for confidence interval is= -0.348
