Step 1

**Introduction:**

The 100 (1 – *α*) % confidence interval for the population mean difference, *μ**d*, for given sample standard deviation of differences, *s**d* in case of paired samples is: (*x̅d* – (*tα*/2; *n* – 1) (*s**d* */√n*), *x̅d* + (*tα*/2; *n* – 1) (*s**d* */√n*)).

Here, *n* is the sample size, *x̅d* is the sample mean difference, and *tα*/2; *n* – 1 is the critical...
