Answer the following question
The level of lead in the blood was determd for a sample of 152 male hazardous waste workers age 20-30 and also for a sample of 85 female workers, resulting in a mean t standard error of 5.3 +0.3 for the men and 3.80.2 for the women. Calculate an estimate of the Merence between true average blood lead levels formale and female workers in a way that provides information about reliability and precision (Use a 95%...

#6. The level of lead in the blood was determined for a sample of 152 male and 86 female hazardous- waste workers resulting in mean t standard error of 5.5 t 0.3 for the men and 3.8 ± 0.2 for the women. (a) Provide a 92% CI on the difference between the true average blood levels for male and female workers (b)Is there sufficient evidence that the true average blood level for male workers exceeds that of female workers by...

Does the amount of hazardous material absorbed by the bodies of hazardous waste workers depend on gender? The level of lead in the blood was determined for a sample of men and a sample of women who dispose of hazardous waste as a full time job. You want to test the hypotheses that the amount absorbed by men is less than the amount absorbed by women. After performing a hypothesis test for two independent samples, you see a p-value of...

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 absorbed by men (group 1) is less than the amount absorbed by women (group 2). A random sample of 231 male workers and 197 female workers showed an average lead absorption in the blood of 12.2 (SD = 0.774) and 12.21 (SD = 0.577), respectively (measured in micrograms/deciliter). Assuming that the population standard deviations...

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 absorbed by men (group 1) is different from the amount absorbed by women (group 2). A random sample of 167 male workers and 188 female workers showed an average lead absorption in the blood of 9.7 (SD = 0.975) and 9.62 (SD = 0.724), respectively (measured in micrograms/deciliter).
