High school students across the nation compete in a financial capability challenge each year by taking a National Financial Capability Challenge exam, students who score in the top 19 percent are recognized publicly for their achievement by the Department of Treasury. Assuming a normal distribution, how many standard deviations above the mean does a student have to score to be recognized?
Use the given data values (a sample of female arm circumferences in centimeters) to identify the corresponding z scores that are used for a normal quantile plot, then identify the coordinates of each point in the normal quantile plot. Construct the normal quantile plot, then determine whether the data appear to be from a population with a normal distribution. 33.9, 37.9, 43.8, 32.8, 40.1 Question content area bottom Part 1 List the z scores for the normal quantile plot.
