Use a 0.05 significance level to test the claim that the mean IQ score of people with low lead levels is higher than the mean IQ score of people with high lead levels. Low Lead Level: n = 78, x= 92.88462, s = 15.34451 High Lead Level: n = 33, x = 86.90476, s = 8.988352 For each of the requirements necessary for this test, choose the correct answer in determining if the are met or not. 1.) The population standard deviations are not equal. This requirement is met. We can used the sample standard deviations to help gauge if the population standard deviations are equal. True/False|[ Select ] 2.) The samples are independent. True/False [ Select ] 3.) Both samples are random samples True/False [ Select ] 4.) The sample sizes are both larger than 30. True/False [ Select ]
