Listed in the data table are 10 scores for a random sample of subjects with medium load levels in their blood. Also listed are statistics from a study done of IQ scores for a random sample of subjects with high lead levels. Assume that the two samples are independent simple random samples selected from normally distributed populations. Do not assume that the population standard deviations are equal. Complete parts (a) and (b) below. Use a 0.05 significance level for both...

A data set 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 is higher than the mean IQ score of people with high lead levels. Low Blood Lead Level: n = 77 x =...

PLEASE HELP ME OUT WITH BOTH QUESTIONS!!! it is greatly appreciated!! thank you so much. no need to show the work. You wish to test the claim that the average IQ score is less than 100 at the .005 significance level. You determine the hypotheses are: Ho:u= 100 H1:4 < 100 You take a simple random sample of 72 individuals and find the mean IQ score is 96.7, with a standard deviation of 15.5. Let's consider testing this hypothesis two...
