3. A London Secondary School is using a different way to determine the highest- Grade Point Average (GPA) for their graduates. They are going to assign weightings to courses based on their perceived difficulty. The weightings table is shown below. Course Weight Factor Math Course 5 Science & English Courses 4 Other Courses 2 Charmander's marks Calculus 88% Data Management 92% English 97% Foods and Nutrition 98% World History 99% Chemistry 96% Charmander and Eevee are the top 2 students, and the highest students will be chosen valedictorian. If Eevee's average is 94%, who will be the valedictorian given Charmander's marks are shown above?c) Identify any outliers. d) Make a box and whisker plot of the oxygen consumption (with or without technology). Label the quartiles and outliers (if any).2. The following set of data relates mean word length and recommended age level for a set of children's books. Recommended Mean Word Age Length 4 3.5 6 5.5 5 4.6 6 5.0 7 5.2 9 6.5 8 6.1 4.9 6.7 a. Calculate the correlation coefficient (to two decimal places) using the table and classify the correlation. b. Use the method of least squares/linear regression to determine the equation of the line of best fit. Round all numerical values to two decimal places. c. Use this model to predict the average word length in a book recommended for 12-year-olds. Is this interpolation or extrapolation? Explain.One and Two Variable Statistics Show all processes and label graphs. 1. The oxygen consumption, in milliliters per minute per kilogram, of 13 heart patients were recorded during an exercise test: 9.7 31.1 15.2 14.6 17.5 12.6 10.4 15.9 14.1 16.2 13.8 12.4 11.0 a) What is the standard deviation for the data? Show the table and the calculation b) What is the IQR
