A large food processing company wants to pack exactly 300 grams of tuna fish in a can .It is known from past experience that the weights of cans have a sample standard deviation of 5 grams.When a sample of size 19 was selected,the sample mean was 301 grams.Using a 5 % level of significance ,test the hypothesis that the average weight is 300 grams . Do both a Neyman -Pearson critical value(cv) test and a p-value test.

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.
