Question

19. Mehl (2007) published in the journal Science the results of an extensive study of 396 men and women, comparing the number of words uttered per day by each sex. Is the population likely to be normally distributed? Why or why not? a. Yes; the population is likely to be normally distributed because the sample size is made up of men and women equally b. No; the population is not likely to be normally distributed because it has a small sample size c. Yes; the population is likely to be normally distributed because the sample is greater than 30 d. We do not know whether the population is normally distributed because we do not have information on the population

Explanation / Answer

d. We do not know whether the population is normally distributed because we do not have information on the population

We can use CLT to say the sample will be approximately normal, but we do not have information about population to say the same.
