Solutions to End-of-Section and Chapter Review Problems 472.60(h) The typical weight for a slice of pizza is between 10 and 20 ounces, where the cumulativepercentage shows 55% of the sample is less than or equal to 20 ounces. The typical cost for a slice of pizza is between $.75 and $1.00, since that is both the most frequently occurring interval and better than 50% of the sample is less than or equal to $1.00. The typical caloric content for a slice of pizza is between 340 and 370 calories, since that is the most frequently occurring interval and better than 70% of the sample is less than or equal to 370 calories. Based on the results of the pairwise scatter diagrams, calories and fat seem to be related. Other variables do not show any particular pattern in the scatter plot, but the graph of calories and fat has a positive slope because it rises from left to right, showing that as one variable increases, the other tends to also increase. The data points are tightly distributed within the cloud of points, indicating that the relationship between calories and fat content is strong.2.62(a) WeightsFrequency3015 but less than 305033050 but less than 3085433085 but less than 31201283120 but less than 31551253155 but less than 3190583190 but less than 322573225 but less than 326033260 but less than 32951Total368(b) WeightPercentage3015 but less than 30500.0081521743050 but less than 30850.1168478263085 but less than 31200.3478260873120 but less than 31550.3396739133155 but less than 31900.1576086963190 but less than 32250.0190217393225 but less than 32600.0081521743260 but less than 32950.002717391Total1(c) % Histogram (Boston)0%5%10%15%20%25%30%35%40%3050 3085 3120 3155 3190 3225 3260 3295Weight (lbs)%(d) About 68% of the Boston Shingles pallet weights fall in the lighter side between 3085 and 3155 pounds.
