The score distribution shown in the table is for all students who took a yearly AP statistics exam. An AP statistics teacher had Score Percent of students 63 students preparing to take the AP exam. Though they were obviously not a random sample, however, the teacher considers the students to be "typical" of all the national students. 13.6 21.7 What is implied by the use of the word "typical"? Assume the probability values shown in the table do not come from a sample of 63 students but rather they represent the actual probabilities for this particular situation. Those probabilities are 25.6 - NWA parameters. 18.3 Answer the questions based on this assumption. 20.8 E (P) =0 (enter as a decimal, not a percentage) SD (P) = (Round SD (p) to five decimal places as needed.) P (p2 0.2678 )= (Round probability to three decimal places as needed.) b) Suppose that instructor has another set of 63 students.What's the probability that 42.46% or more of his students score at least a 4 on the AP statistics exam, from a sample of 63 students? E (p) =(enter as a decimal, not a percentage) SD (p) = (Round SD (p) to five decimal places as needed.) P (p2 0.4246 )=. (Round probabilty to three decimal places as needed.)
