Answer:
Standard error = 0.34
t-statistic = 11.18
Step-by-step explanation:
Given Data:
Mean difference d = 3.8
Standard deviation S.D = 1.36
Number of people = 16
The appropriate test are:
1. Standard error
2. T- statistic
1. Calculating the standard error using the formula;
Standard error = S.D/√n
                          = 1.36/√16
                           = 1.36/4
                            = 0.34
2. Calculating the t-statistic using the formula;
t-statistic = d/(S.D/√n)
               = 3.8/(1.36/√16)
               = 3.8/(1.36/4)
               = 3.8/0.34
                = 11.18
