Statistics Ch. 6 Test REVIEW Name: KEY Date: Part 1: Multiple Choice (2 points each) Here are the means and standard deviations of the weights of two groups of cats. Which statement is true? Al the cats in group B weigh less than all the cats in group A. The weights of each group follow a Normal model. A 3.3 pound cat in group B is closer to average than an 8.2 pound cat in group A. Compared to group B, the weights in group A are closer to the mean. In a Normal model, what percent of data is between -1 and +2 standard deviations of the mean? 68 81.5 99.7 It depends upon the standard deviation Normal model A has a smaller standard deviation than Normal model B. How do the graphs of these models compare when drawn on the same scale?

From experience, the owner of an ice-cream shop has found that 60% of all sales of ice-cream cones are for one-scoop cones, 30% are for two-scoop cones, and the remaining 10% are for three-scoop cones. Recently, the shop added frozen-yogurt cones to its menu. A random sample of 250 sales of frozen-yogurt cones revealed the following distribution: The owner wishes to know whether the pattern of sales for frozen-yogurt cones differs from that of ice-cream cones. In a goodness-of-fit test based on the ?2 distribution, the expected count for "number of two-scoop frozen-yogurt cone sales" would be A. 84. B. 75. C. 83.33.
