Listed in the data table are IQ scores for a random sample of subjects with medium lead 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. Click the icon to view the data table of IQ scores. a. Use a 0.01 significance level to test the claim that the mean IQ scores for subjects with medium lead levels is higher than the mean for subjects with high lead levels. What are the null and alternative hypotheses? Assume that population 1 consists of subjects with medium lead levels and population 2 consists of subjects with high lead levels. OA.

This histogram shows the heights of 20 students in a statistics class. Explain why it is not appropriate to find summary statistics for this distribution. Frequency 4- 3- 2- 1- T 0+ 60 65 70 75 Height (Inches) Choose the correct answer below. OA. Since there appear to be two modes, this data probably represents men and women and should be split into those two groups before finding any summary statistics. OB. The number of data values is too small for summary statistics to be meaningful. OC. Since the data appear to be bimodal, no other measures of center or spread can be calculated. OD. Since the distribution is not symmetric, summary statistics would be meaningless.

Assume that the SAT test scores are normally distributed with a mean score of 1200 and a standard deviation of 150. ACT test scores are normally distributed with a mean score of 22 and a standard deviation of 3 Mike scored 1250 on the SAT. What proportion of all test takers did Mike score higher than? If Mike scored a 1250 on the SAT and Jes scored a 26 on the ACT, then who's score is relatively better?
