Solution:-
Given data is as below:-


Now consider from the above table,
sample size, n = 12
sample mean for the differences, d- =  =   = -0.03008 = -0.030
standard deviation for difference scores, sd =   =   = 0.029889 = 0.0299

(c)  = -0.030
sd = 0.0299

Read the given data and note the information.
Substitute values of data in the formulas of mean and standard deviation to execute them.
