Listed in the data table are amounts of strontium-90 (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. Complete parts (a) and (b) below. E Click the icon to view the data table of strontium-90 amounts. a. Use a 0.01 significance level to test the claim that the mean amount of strontium-90 from city #1 residents is greater than the mean amount from city #2 residents. What are the null and alternative hypotheses? Assume that population 1 consists of amounts from city #1 levels and population 2 consists of amounts from city #2. OB. Ho: H1 #H2 H,: Hy> H2 O A. Ho: H1= H2 H H #H2 D. Ho H1= H2 OC. Ho: H1S H2 H: H1 > H2 H: H1> H2 The test statistic is (Round to two decimal places as needed.)
