The score distribution shown in the table is for all students who took a yearly AP statistics exam. An AP Score statistics teacher had 65 students preparing to take the AP exam. Though they were obviously not a random Percent of students sample, however, the teacher considers the students to be "typical" of all the national students. Answer the 13.7 questions based on this assumption. 22.1 24.8 17.4 22.0 a) What's the probability that 32.27% or more of his students will achieve a score of 4? The techniques that you are using in this chapter are referred to as normal approximations. E (p) =(enter as a decimal, not a percentage) SD(P) = (Round SD (p) to five decimal places as needed.) P (p2 0.3227 )= ]. (Round probability to three decimal places as needed.) b) What's the probability that 50.12% or more of his students score at least a 4 on the AP statistics exam? E (p) =(enter as a decimal, not a percentage) SD (P) = (Round SD (p) to five decimal places as needed.) P (p2 0.5012 )=]. (Round probabilty to three decimal places as needed.)
