Assuming that the population standard deviations are the, Ask an Expert

Statistics

Does the amount of hazardous material absorbed by the bodies of hazardous waste workers depend on gender? You want to test the hypotheses that the amount absored by men (group 1) is different from the amount absorbed by women (group 2). A random sample of 259 male workers and 118 female workers showed an average lead absorbtion in the blood of 14.65 (SD = 0.633) and 14.67 (SD = 0.794), respectively (measured in micrograms/deciliter). Assuming that the population standard deviations are the same, perform a two independent samples t-test on the hypotheses Null Hypothesis: μ1 = μ2, Alternative Hypothesis: μ1 ≠ μ2. What is the test statistic and p-value of this test?

1) Test Statistic: -0.262, P-Value: 0.3968

2) Test Statistic: -0.262, P-Value: 0.6033

3) Test Statistic: 0.262, P-Value: 0.7935

4) Test Statistic: -0.262, P-Value: 1.6033

5) Test Statistic: -0.262, P-Value: 0.7935
