Listed in the data table are amounts of strontium-Bl] [in millibecquerels, or mBq, per gram of calcium} in a simple random sample of baby teeth
Listed in the data table are amounts of strontium-Bl] [in millibecquerels, or mBq, per gram of calcium} in a simple random sample of baby teeth obtained from residents in two cities. 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. Use a 0.05 signicance level to test the claim that the mean amount of strontium9i] from city #1 residents is greater than the mean amount from city #2 residents.
