Find a p-value for the following hypothesis test and determine whether reject or fail to reject the null hypothesis at 2% significance level.

H1: σ ≠ 19.93

Sample size is 25, and the test statistic is 50.744

show formulas and draw all curves.

Definition Definition Number of subjects or observations included in a study. A large sample size typically provides more reliable results and better representation of the population. As sample size and width of confidence interval are inversely related, if the sample size is increased, the width of the confidence interval decreases.
