1. A polling company takes a nationwide survey asking people whether they favor stricter laws on the sale of cigarettes. They find that 45% agree 35% disagree in 20% or undecided. In a more local simple random sample of size 200 110 say they favor stricter laws 60 are opposed and 30 have no opinion. You're interested in whether these results differ significantly from the national findings. Which of the following gives he said of expected values for the X^2 test for goodness-of-fit? A. 90, 70 ,40 B. 8.373, 1.4286, 2.5 C. 20, -10, -10 D. 110, 60, 30 2. We have a bi variate data set and compute the following r= .7, sy= 9, sx= 5, x hat= 13.5, y hat= 51.6. We want to know the equation of the least squares regression line but we don't have a calculator that's powerful enough to do the necessary computations. Determine the equation of the least squares regression line from the given data A. y hat= -6.624 + .39x B. y hat= -51.52 + 1.26x C. You can't compute the regression line without knowing the original data D. y hat= 34.59 + 1.26x 3. For a X2 test of independence and researcher computes a X2 value of 22.5. The two way table from which this value was computed had five rows and four columns. What's the P value for this statistic? A. .10

.25 C. .025
