Chapter 6: Q.6.124 (page 283)

We have provided a normal probability plot of data from a sample of a population. In each case, assess the normality of the variable under consideration.

Short Answer

Expert verified

The plot does not have a nearly normal distribution.

Step by step solution

01

Given Information

Consider the probability of the normalcy plot.

02

Explanation

The data is not distributed along a straight line, as evidenced by the given normality probability plot. As a result, the plot does not appear to be roughly normal.

A variable is normally distributed with a mean 68and standard deviation 10. Find the percentage of all possible values of the variable that

a. lie between 73and 80.

h. are at least 75.

c. are at most 90.

Philosophical and health issues are prompting an increasing number of Taiwanese to switch to a vegetarian lifestyle. In the paper "LDL of Taiwanese Vegetarians Are Less Oxidizable than Those of Omnivores" (Journal of Nutrition, Vol. 130, Pp. 1591-1596), S. Lu et al. compared the daily intake of nutrients by vegetarians and omnivores living in Taiwan. Among the nutrients considered was protein. Too little protein stunts growth and interferes with all bodily functions; too much protein puts a strain on the kidneys, can cause diarrhea and dehydration, and can leach calcium from bones and teeth. The daily protein intakes, in grams, for 51 female vegetarians and 53 female omnivores are provided on the Weiss Stats site. Use the technology of your choice to do the following for each of the two sets of sample data.

a. Obtain a histogram of the data and use it to assess the (approximate) normality of the variable under consideration.

b. Obtain a normal probability plot of the data and use it to assess the (approximate) normality of the variable under consideration.

c. Compare your results in parts (a) and (b).

Students in an introductory statistics course at the U.S. Air Force Academy participated in Nabisco's "Chips Ahoy! 1.000 Chips Challenge" by confirming that there were at least 1000 chips in every18-ounce bag of cookies that they examined. As part of their assignment, they concluded that the number of chips per bag is approximately normally distributed. Could the number of chips per bag be exactly normally distributed? Explain your answer. [SOURCE: B. Warner and J. Rutledge, "Checking the Chips Ahoy! Guarantee," Chance, Vol. 12(1). pp. 10-14]
