Suppose you evaluate the effectiveness of an SAT tutoring course for 10 students who plan to retake the standardized exam. Below lists the number of points that each student gained on the exam after taking the tutoring course: 450, 950, 780, 800, 750, 880, 800, 680, 600, 990 using the data analysis function, find the "descriptive statistics" using the data analysis function, create histogram and frequency distribution (create bins starting with the lowest score of 450, and then count by tens until the maximum score of 990) to review for the Unit 2 Exam - using the mean and standard deviation you found using Excel, what is the Z-score for X = 800 or greater. Now from that z-score, what is the probability of earning 800 pts or more if you take that SAT tutoring course?
