Question 13 5 pts Data lists full IQ scores for a random sample of subjects with low lead levels in their blood and another random sample of subjects with high lead levels in their blood. The statistics are summarized below. Use a 0.05 significance level to test the claim that the mean IQ score of people with low lead levels in their blood is different from those with high lead levels in their blood. Let M1 represent low lead level. Low Lead Level: n = 25 X = 91.90476 S = 9.988352 High Lead Level: n = 74 x = 89.89462 s = 12.34451 Determine the p-value and which type of test is required. p= .8172 and a two tailed test O p = .4176 and a right tailed test p = .8172 and a right tailed test p = .4176 and a two tailed test
