1. Refer to the Excel "SAT" data posted in Canvas. (20) a. What is the mean, median, and 40th percentile SAT score amongst all students in the sample? (you might refer to our Descriptive Statistics Chapter Slides on calculating the percentile). Create a histogram of the students based on "bin" widths 200 units wide starting with 1001-1200. b. What is the mean, median, and 40th percentile SAT score amongst Godby students in the sample? Create a histogram of the students based on "bin" widths 200 units wide starting with 1001-1200. c. What is the mean, median, and 40" percentile SAT score amongst Lincoln students in the sample? Create a histogram of the students based on "bin" widths 200 units wide starting with 1001-1200. d. What is the probability that a randomly selected Godby student has an SAT score > 1601? What is the probability that a randomly selected Lincoln student has an SAT score > 1601? Based on your calculations, comment, if you can, on whether SAT score is statistically independent of school
