Question

em #5: A researcher wanted to test if the median amount of cereal in all ABC Company cereal boxes is less than the advertised 16 grams A random sample of $n = 8$ boxes yielded. Cereal (grams) 13 14 14 13 15 17 15 16 a.) Compute the $p$ value b.) Rework a.) using $M \approx N \left( \mu = \frac{n}{2}, \sigma^2 = \frac{n}{4} \right)$ c.) Suppose the two 13 and the two 14 observations were switched to 15's. How would the $p$ value of the test be impacted?
