Question 1) A group of reviewers tested the quality of a product. The evaluation was to grade the quality of product on a 0-to-100-point scale. The results follow. Construct a stem and leaf diagram for these data and comment on any important features that you notice. Compute the sample mean, the sample standard deviation, and the sample median. A product rated above 90 is considered as best quality product. What proportion of the reviewers considered this particular product as best quality product? 95 90 92 91 91 86 89 91 91 90 90 94 87 90 91 92 89 86 89 90 88 95 90 88 89 92 87 89 95 92 85 91 85 88 88 84 85 90 90 83 Question 2) Construct a histogram for the product rating data in Question 1. Comment on the shape of the his- togram. Does it convey the same information as the stem and leaf display?
