Assume that a randomly selected subject is given a bone density test. Those test scores are normally distributed with a mean of 0 and a standard deviation of 1. Draw a graph and find the bonedensity test scores that can be used as cutoff values separating the lowest 9% and highest 9%, indicating levels that are too low or too high, respectively.Sketch the region containing the lowest 9% and highest 9%.

2. For the data set below, do a complete boxplot analysis. This includes finding the quartiles, the range, the interquartile range, inner fences, and outer fences. Make sure you draw the graph. Then tell me whether the highest observation is reliable, a mild outlier, or an extreme outlier. 9, 11, 13, 14, 16, 17, 17, 18, 19, 20, 35.
Eyeglassomatic manufactures eyeglasses for different retailers. They test to see how many defective lenses they made the time period of January 1 to March 31. The table gives the defect and the number of defects. Do the data support the notion that each defect type occurs in the same proportion? Test at the 5% level.

Conduct the hypothesis test and provide the test statistic and the critical value, and state the conclusion. A person purchased a slot machine and tested it by playing it 1,105 times. There are 10 different categories of outcomes, including no win, win jackpot, win with three bells, and so on. When testing the claim that the observed outcomes agree with the expected frequencies, the author obtained a test statistic of χ2=18.392. Use a 0.05 significance level to test the claim that the actual outcomes agree with the expected frequencies. Does the slot machine appear to be functioning as expected?
