Chapter 2 Ap Statistics Practice Test Pdf Normal Distribution Study with quizlet and memorize flashcards containing terms like many professional schools require applicants to take a standardized test. suppose that 1000 students take such a test. several weeks after the test, pete receives his score report: he got a 63, which placed him at the 73rd percentile. this means that, for the normal distribution shown, the standard deviation is closest to. To find the area to the right, subtract the value in the table from 1. birth weights of babies in the united states can be modeled by a normal distribution with mean 3250 grams and standard deviation 550 grams. those weighing less than 2500 grams are considered to be of low birth weight.
Ap Stat Unit 2 Section 2 2 The Normal Distribution Pdf A. 4.81 inches. b. 5.18 inches. c. 6.04 inches. d. 8.93 inches. e. the standard deviation cannot be computed from the given information. a. 4.81 inches. begin by finding the z score that determines the upper 15% in a normal. distribution (area to the left of that z score must be 85% or .8500). A. the area under a normal curve is always equal to 1, no matter what the mean and standard deviation are. b. all bell shaped curves are normal distributions for some choice of μ and σ. c. the smaller the standard deviation of a normal curve, the lower and more spread out the graph.
