Normal Distribution Pdf Normal Distribution Histogram Normal distribution practice problems (6c) some of these problems require that you use the z table found in your book. others should be solved by using the empirical rule (68% 95% 99.7%). note that anytime the z score is –3, 2, 1, 1, 2, or 3 you can use the empirical rule. To summarize the problems so far, here are the two cases that you will encounter in all of the problems dealing with normal distribution. compare what is given, what you need to find in both cases, and the strategies to solve both problems. A test was given to 120 students, and the scores approximated a normal distribution. if the mean score was 72 with a standard deviation of 7, approximately what percent of the scores were 65 or higher?. A random variable, z, which has this p.d.f. is denoted by z ~ n ( 0,1 ) showing that it is a normal distribution with mean 0 and standard deviation 1. this is often referred to as the standardised normal distribution.

A shop foreman found that it takes 40 minutes on average to complete a specific task. given that the standard deviation for this task is 5 minutes and the times for completing this task are normally distributed, what percentage of completions will take 50 minutes or more?. 34. kidney transplant waiting times the time spent (in days) waiting for a kidney transplant for people ages 35 49 can be approximated by a normal distribution, as shown in the figure.
