Problem
A researcher is interested in whether male or female great white sharks eat more fish. To make an inference about the population of sharks, the researcher gathered a sample of 14 female sharks and 12 male sharks and counted the number of fish they ate over a weeks time. On average female great white sharks ate 6740 fish (standard deviation, 1203) a day, male sharks
Ate an average of 7543 fish (standard deviation, 1543) a day. Using an alpha level = .05, is there a difference in the average amount of fish eaten by male and female sharks?
• Step I: State the Null and Research Hypotheses
• Step II. Determine the degrees of freedom and determine t-critical
• Step III. Obtain the Data and compute the test statistic.
