Purpose:To see the variation of outcomes when we select a random sample from the set of numbers 1 to 100.To practice the module objectives "Describe the distribution of the sample mean for normal populations" and "Find and interpret the area under a normal curve"

Skills:Using technology to produce a set of random integers.Using technology to calculate normal probabilities.

Knowledge:This assignment will help you see the natural variation of means from a set.You'll also practice calculating normal probabilities, using your calculator.

Task:

Our population is the data set with values 1 to 100.The mean of the set is 50.5 and the SD is 29.01

1.Individually:Use the MATH-PRB-randInt command (1 to 100, pick 5) to get a random sample of 5 values from the set.In the table below, write down your sample and the mean of that sample.Do 4 times.
