According to a research study, the average weight of a baby shark is 15.7 kilograms. A random sample of 13 baby sharks has a mean weight of 16.8 kilograms and a standard deviation of 2 kilograms. Assume that the population weights are normally distributed. Which answer choice shows the correct first three steps to performing a one-mean hypothesis test at the 1% significance level if we want to test whether the average weight of a baby shark is greater than the weight predicted by the research study?
