The statement makes sense For a normal dstributon 50 percent of the men should have pulse rates above re mean O B. The stotement does not make sense because a pulse rates are a combination of many different factors, such as genetic and environmental factors, and are therafore unikely to yield normally distributed values O C. The statement does not make sense For a normal distribution only hailf of the men should have pulse rates above the mean D. The statement makes sense because such a large sample wd almost always be normally distributed ck An

Explanation / Answer

As n=993 which is sufficient large and as per central limit theorem, states that if you have a population with mean and standard deviation and take sufficiently large random samples from the population with replacement , then the distribution of the samplemeans will be approximately normally distributed.

Hence answer is D. The statement makes sense because such a large sample will almost always be normally distributed.
