Problem 2: Great white sharks are big and hungry. The dataset 'Sharks.csv' contains the lengths (in feet) of 44 great whites. a.State two things you would like to know about these data that would help with the analysis and conclusions. b.Create a normal Q-Q plot of the shark lengths. Do the data appear to be approximately normally distributed? c.Create a histogram of the data. Do you notice any outliers? (NOTE: the argument breakswill change the number of bins/cells for the histogram. Try different values such as breaks 7, breaks-12. Note the number of observations is 44 so do not create too many bins). d.Find the sample mean and sample standard deviation of the data. e.You believe Great Whites average over 15 feet in length. To test this claim, what would be the null and alternative hypothesis? f.Calculate the appropriate test statistic g.What is the p-valuefor the test statistic calculated in part f? h.What is the conclusion of the test at the a-0.10 significance level? State in terms of the question. i.Give a 90% confidence interval for the mean length of great white sharks. length 18.7 12.3 18.6 16.4 15.7 18.3 14.6 15.8 14.9 17.6 12.1 16.4 16.7 17.8 16.2 12.6 17.8 13.8 12.2 15.2 14.7 12.4 13.2 15.8 14.3 16.6 9.4. 18.2 13.2 13.6 15.3 16.1 13.5 19.1 16.2 22.8 16.8 13.6 13.2 15.7 19.7 18.7 13.2 16.8 Problem 2: Great white sharks are big and hungry.
