Problem 5BSC

In Exercise? ?use analysis of variance for the indicated test. Lead and Verbal IQ Scores? Example 1 used measured ?performance? IQ scores for three different blood lead levels. If we use the same three categories of blood lead levels with measured ?verbal IQ? scores, we get the accompanying Mini tab display. (The data are listed in Data Set 5 of Appendix B.) Using a 0.05 significance level, 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? Example 1? Lead and Performance IQ Scores

Step-by-Step Solution:

Solution 5BSC Step 1 The given problem explain about lead and verbal IQ scores. Here,the three categories of null hypothesis have same mean verbal IQ scores or = = . 1 2 3 We know that the significance level of =0.05 Then the P-value = 0.677 (from the minitab table) Hence the P-value > the significance level of =0.05 Therefore 0.677 > 0.05 So,we cannot reject the null hypothesis of = 1 = 2. 3 Hence we...
