6.2 The Standard Normal Distribution Table: Z-score and Probability In the country of United States of Heightlandia, the height measurements of ten-year-old children are approximately normally distributed with a mean of 53.7 inches, and standard deviation of 5.1 inches. What is the probability that the height of a randomly chosen child is between 40.95 and 43.35 inches? Probability = (Use 4 decimal places.)

Scores on the verbal Graduate Record Exam (GRE) are normally distributed with a mean of 600 and a standard deviation of 120. Suppose a graduate school requires that students score at or above the 80th percentile. Approximately what score is required on this exam? b.Practice using the 68-95-99.7 Rule by completing the normal distribution belowwith horizontal scale and percentages in each interval. [Use the graph in (c) and (d).]
The time that it takes for the next train to come follows a Uniform distribution with f(x) =1/50 where x goes between 2 and 52 minutes. Round answers to 4 decimal places when possible. A. This is a Uniform or Normal distribution? B. Is it a Discrete or Continuous distribution? C. What is the mean of this distribution?
An elevator can safely hold 3500 pounds. A sign in the elevator limits the passenger count to 15. If the adult population has a mean weight of 180 pounds with a 25-pound standard deviation, how unusual would it be, if the central limit theorem applied, that an elevator holding 15 people would be carrying more than 3500 pounds? Note. Use pnorm which is the normal distribution function of R.
