(Answered) Listed in the data table are iq scores for a random sample

Economics

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 Lead Level: 72,84,92,85,82,97,83,92,101,111,91

High Lead Level: n₂=11,x₂=88.110; s₂=10.352

Construct a confidence interval suitable for testing the claim that the mean IQ scores for subjects with medium lead levels is higher than the mean for subjects with high lead levels.

Your answer should use interval notation.

(Round to three decimal places as needed.)
