In a test of H0: p = 0.7 against Ha: p z 0.7, a sample of size 80 produces z = 0.8 for the value of the test statistic. Which of the following is closest to the P-value of the test? (a) 0.2090 (b) 0.2119 (c) 0.4238 (d) 0.4681 (e) 0.7881 2. An opinion poll asks a simple random sample of 100 college seniors how they view their job prospects. In all, 53 say ?good.? Does the poll give convincing evidence to conclude that more than half of all seniors think their job prospects are good? If p = the proportion of all

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?
