%3D Suppose IQ scores were obtained for 20 randomly selected sets of siblings. The 20 pairs of measurements yield x = 99.21, y = 101.2, r= 0.698, P-value = 0.000, and y = 21.92 + 0.8x, where x represents the IQ score of the older child. Find the best predicted value of y given that the older child has an IQ of 92? Use a significance level of 0.05. Click the icon to view the critical values of the Pearson correlation coefficient r. The best predicted value of y is. (Round to two decimal places as needed.)

You are playing a dice game with a friend and become suspicious that he is using weighted dice. So you stop the game, take one of his dice, and roll it 100 times. The results are in the table below. Do these results provide significant evidence that the proportion of times the dice lands on the six numbers are unequal? Calculate the chi-squared test statistic and the range the p-value falls in for this test. Number on die 1 2 4 Frequency 16 21 6 26 13 18 test statistic = 14.12, p-value in (.01, .025) test statistic = 24.368, p-value in (.005, .01) test statistic = 14.12, p-value in (.025, 05) test statistic = 24.368, p-value less than .005 O none of these

IQ scores for three different blood lead levels was measured. If we use three categories of blood lead levels with measured verbal IQ scores, we get the computer output which is summarized in table form. Using a 0.05 significance test, test the claim that the three categories of blood lead level have the same mean verbal IQ score. Does exposure to lead appear to have an effect on verbal IQ scores? Interpret the table below. Source of variation df Sum of squares Mean squares Computed f p-value LEAD 2 142 71 0.39 0.677 Error 118 21441 182 Total 120 21584
