The average height for a population of 10 year olds is 54.5 inches with a standard deviation of 1.8 inches. A sample of 10 children is randomly chosen and found to have a standard deviation in height of 2.1. x^2 = 12.25 for this scenario.

What is the probability that another randomly chosen sample of 10 children would have a standard deviation in height of less than 2.1 inches? Type in this format #.###
