15 The x and y data are sample data from the population of X and Y to compute b, as an estimate of the population slope parameter B1. The sample statistic b, is the estimator of the population parameter B1. The estimated measure of dispersion of the sample statistic bj is, a 0.6262 b 0.5218 C 0.4348 d 0.3624 16 The margin of error for a 95% confidence interval for B, is, 0.9646 b 0.8769 C 0.7972 0.7248 17 To perform a hypothesis test with the null hypothesis Ho: B1 = 0, we need a test statistic. The test statistic for this hypothesis test is, a 5.723 b 4.977 4.328 3.763Questions 1-17 are related to the following Below are the values for two variables X and y obtained from a sample. We want to build a regression equation based the sample data. y = 160 + 61x 2 X 44.3 7.6 18.9 5.3 30.4 7.8 22.3 4.2 19.8 4.8 27.5 7.7 21.8 7.6 27.6 5.8 46 11.5 27.5 7.8 26.1 6.6 35.4 11.2 38.6 12.6 43.1 10.4 26.9 7.9 34 10.4 19.3 4.8 48.1 9.4 40.9 8.3 46.5 13.3 30.6 10.2 18.5 5.1 43.1 9 35.9 8.6 51.2 12.4 38.9 6.7 33.3 12.9 35.7 9.3 27.3 9.3 34 9.4 20.7 4.6 45.6 10.1 43.6 6.4 32.1 12.1 35.4 6.2 26.1 7.3 22.7 6.2 29.6 6.9 31.9 9.4 27.3 7.8 36.9 8.6 31.9 10 20 4.8 47.8 8.7 31.6 8.2
