Health And Nutrition Examination Survey

National Health?

The national survey on health and Nutrition examination 1976-80 found that the serum level cholesteral average for American men aged 20-74 years was 211. The standard deviation was approx. 90. Consider the sampling distribution the sample means from samples of size 100 drawn from the male populationof. A. What are the averages and standard deviations the sampling distribution? b.Is necessary for the original distribution to be normal? C. Explain Suppose a random sample of 100 is taken, what is the probability that the mean seroma cholesteral level will be between 198 and 220?

a. The average is the same as far as we can tell whether your standard error = 90/sqrt (100) = 9 B. No, because the central limit Therom states that as obtain samples large enough (generally higher 30) of their distributions become almost normal for this last part you need the SE, we just c. Calculated z = (198-211) / 9 = 3333 -. z = (220-211) / 9 = 1 p associates from z -. 333 = 0.369453984 p associates from 1.0 z = 0.84134474 subtract the two and get 0.471890757
