A study was done that measured the body weight in grams of guinea pigs at birth.
(a) Set up the appropriate Hypotheses test that the mean body weight is 300 grams or not.
(b) State which Test Statistic needed to test the above hypotheses and whether it is one sided or two sided.
(c) Calculate the needed summary statistics and report them. Then calculate the Test Statistic, showing the formula first, then plugging in the right numbers and giving the result.
(d) Show how to calculate your P-Value, drawing a small sketch of the proper distribution, labeling which one it is, and then use α = 0.05, find the actual P-value and write out a Conclusion in the context of the problem.
