1. Weights of Steaks A student of the author weighed a simple random sample of Porter-house steaks, and the results (in ounces) are listed below. The steaks are supposed to be 21 oz because they are listed on the menu as weighing 20 ounces, and they lose an ounce when cooked. Use the listed weights to find the (a) mean; (b) median; (c) mode; (d) midrange;(e) range; (f) standard deviation; (g) variance; (h) Q1; (i) Q3. 17 19 21 18 20 18 19 20 20 21Q
2. Boxplot Using the same weights listed in Exercise 1, construct a boxplot and include the values of the 5- number summary.
3. Ergonomics When designing a new thrill ride for an amusement park, the designer must consider the sitting heights of males. Listed below are the sitting heights (in millimetres) obtained from a simple random sample of adult males (based on anthropometric survey data from Gordon, Churchill, et al.). Use the given sitting heights to find the (a) mean; (b) median;(c) mode; (d) midrange; (e) range; (f) standard deviation; (g) variance; (h) Q1; (i) Q3. 936 928 924 880 934 923 878 930 936
