I would need some assistance with problem twenty-three, please? Testing for a Linear Correlation. In Exercises 13–28, construct a scatterplot, and findthe value of the linear correlation coefficient r. Also find the P-value or the critical valuesof r from Table A-6. Use a significance level of a = 0.05. Determine whether there issufficient evidence to support a claim of a linear correlation between the two variables.(Save your work because the same data sets will be used in Section 10-2 exercises.) 23. Weighing Seals with a Camera Listed below are the overhead widths (cm) of sealsmeasured from photographs and the weights (kg) of the seals (based on “Mass Estimationof Weddell Seals Using Techniques of Photogrammetry," by R. Garrott of Montana StateUniversity). The purpose of the study was to determine if weights of seals could be deter-mined from overhead photographs. Is there sufficient evidence to conclude that there is alinear correlation between overhead widths of seals from photographs and the weights ofthe seals?Overhead Width7.27.49.89.48.88.4Weight116154245202200191

The teacher from Problem 21 also tried a different approach to determining whether changing answers helps or hurts exam grades. In another class, students were told to review their final exams and change any answers they wanted to before turning them in. However, the students had to indicate both the original answer and the changed answer for each question. The teacher graded each exam twice, once using the set of original answers and once with the changes. In the class of n- 22 students, the exam scores improved by an average of MD - 2.5 points with the changed answers. The standard deviation for the difference scores was s = 3.1. Are the data sufficient to conclude that rethinking and changing answers can significantly improve scores? Use a one-tailed test at the .01 level of significance.

A researcher believed that the number of rental cars in service by a car rental company would have an impact on the total annual revenue for that car rental company. Five small car rental companies were surveyed, with the number of Cars in service recorded in units of 1000 (so if a car rental company had 54000 cars in service, a 54 would be recorded) and Annual Revenue measured in millions of dollars (so an Annual Revenue of $10,000,000 would be recorded as 10).

During his short stint as Shadow Finance Minister, Barnaby Joyce displayed a curious grasp of numbers. One of his most infamous exclamations was “All this billions, quillions, Brazilians.” Less well known was his tax-reform proposal, recommending that if you earn $x per day, you are taxed x% of that amount (with the understanding that you pay 100% tax if you earn $100 or more per day. Under Senator Barnaby’s plan, which amount x gives you the highest earnings after tax has been taken out?
