Chapter 6: Q.6.123 (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 data is not normally distributed, and there are outliers.

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 data is not normally distributed, and there are outliers.

Elephant Pregnancies. G. Wintemeyer et al. studied demographic data on African elephants living in Kenya in the article "Comparative Demography of an At-risk African Elephant Population (PLOS ONE, Vol. 8. No. 1). Based on this study, we will assume that the time between pregnancies of the African elephant in Kenya, for elephants that have more than one calf, is normally distributed with mean of 4.01 years and a standard deviation of 0.94 years. Determine the percentage of such times that are

a. less than 2 years.

b. between 3 and 5 years.

College-Math Success. Researchers S. Lesik and M. Mitchell explore the difficulty of predicting success in college-level mathematics in the article "The Investigation of Multiple Paths to Success in College-Level Mathematics" (fraternal of Applied Reacuwh in Hreher Eiturarion, Vol. 5. Issue 1. pP, 48-57). One of the variables explored as an indicator of success was the length of time since a college freshman has taken a mathematics course. The article reports that the mean length of time is 0.18 years with a standard deviation of 0.624 years. For college freshmen, let x represent the time, in years, since taking a math course.

A . What percentage of times are at least 0 years?

b. Assuming that x is approximately normally distributed, tose normal curve areas to determine the approximate percentage of times that are at least 0 years.

c. Based on your results from parts (a) and (b), do you think that the length of time since taking a math course for college freshmen is approximately a normally distributed variable? Explain your answer.

20. Sketch the normal curve having the parameters

a. 渭=-1and蟽=2

b. 渭=3and蟽=2

c. 渭=-1and蟽=0.5

Use Table to obtain the areas under the standard normal curve. Sketch a standard normal curve and shade the area of interest in each problem.

Find the area under the standard normal curve that lies

a. either to the left of -2.12or to the right of 1.67.

b. either to the left of 0.63or to the right of 1.54.

The area under a density curve that lies between 5 and 6 is 0.728. What percentage of all possible observations of the variable are cither less than 5 or greater than 6 ?
