Homework Answers
b) It is theoretical in nature.
This is not true in the case of the normal distribution and it follows the empirical rule. It forms a bell shaped curve and is symmetrical in nature. It shows how the values of the variables are distributed.

19. Assume that pulse rates of men follow a bell-shaped (normal) distribution with a mean of 74 beats per minute and a standard deviation of 12 beats per minute. a. Based upon the Empirical Rule, give an interval that contains about 95% of all such pulse rates. this has to be solved using excel functions (new versions)

A particular population, for which the frequency curve is bell-shaped (normal), has a mean of μ=100 and a standard deviation of σ=18. For samples of size n=36 consider the sampling distribution of the sample mean ("xbar"). The mean of the sampling distribution of the sample mean is __________ . Group of answer choices 36 3 None of the other choices represent a suitable response. 100 18

Which of the following is NOT a true statement? A. Like the z distribution, the t distribution is bell shaped, symmetrical, and centers around 0. B. The t distribution is flatter and has fatter tails than the z distribution, which makes it more appropriate for the greater sample-to-sample variability in small samples C. Like the z distribution, there is only one t distribution. D. With sample sizes of 120 or more, the t distribution becomes virtually identical to the z...
