Chapter 2: Q 83. (page 143)

Refrigerators Refer to Exercise 75

a. Use your calculator to make a Normal probability plot of the data. Sketch this graph on your paper.

b. What does the graph in part (a) imply about whether the distribution of refrigerator capacity is approximately Normal? Explain.

Short Answer

Expert verified

Part (a) The graph is

Part (b) Yes.

Step by step solution

01

Part (a) Step 1: Given information

The data set is:

12.913.714.114.214.514.514.614.715.115.2
15.315.315.315.315.515.615.615.81616
16.216.216.316.416.516.616.616.61717
17.217.417.417.918.4




02

Part (a) Step 2: Explanation

The normal probabilities plot can be constructed as

03

Part (b) Step 1: Explanation

All of the points in the above plot are within the boundary, implying that the distribution is essentially normally approximated. As a result, the data can be said to have been collected from a regularly distributed population.

Most popular questions from this chapter

Brush your teeth The amount of time Ricardo spends brushing his teeth follows a Normal distribution with unknown mean and standard deviation. Ricardo spends less than one minute brushing his teeth about 40%of the time. He spends more than two minutes brushing his teeth 2%of the time. Use this information to determine the mean and standard deviation of this distribution.

Lefties (1.1) Students were asked, 鈥淎re you right-handed, left-handed, or ambidextrous?鈥� The responses (R=right-handed, L=left-handed, A=ambidextrous ) are shown here.

a. Make an appropriate graph to display these data.

b. Over 10,000 Canadian high school students took the Census At School survey that year. What percent of this population would you estimate is left-handed? Justify your answer.

Step right up! A dot plot of the distribution of height for Mrs. Navard鈥檚 class is shown, along with some numerical summaries of the data.

Suppose that Mrs. Navard has the entire class stand on a 6-inch-high platform and then asks the students to measure the distance from the top of their heads to the ground.

a. What shape would this distribution of distance have?

b. Find the mean and median of the distribution of distance.

c. Find the standard deviation and interquartile range (IQR) of the distribution of distance.

Long jump Refer to Exercise 21 Suppose that the corrected long-jump

distances are converted from centimeters to meters (note that 100cm=1m ).

a. What shape would the resulting distribution have? Explain your answer.

b. Find the mean of the distribution of corrected long-jump distance in meters.

c. Find the standard deviation of the distribution of corrected long-jump distance in meters.

Runners鈥� heart rates The following figure is a Normal probability plot of the heart rates of 200male runners after 6 minutes of exercise on a treadmill.14 Use the graph to determine if this distribution of heart rates is approximately Normal.
