#5 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. Medium led level 72869285909783929511191 High led level n2= 11 x over bar2=90.002 s2= 9.639 the test statistic is P-Value conclusion for test construct a confidence interval suitable for testing the claim that the mean IQ score for subjects with medium lead levels is higher then the mean for subjects with high lead levels. does the confidenc einterval support the conclusion
