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.

a. Shape

b. Mean and median

c. Standard deviation and interquartile range (IQR)

Used cars, cheap! Refer to Exercise 24Suppose each car’s price is reduced by 10% instead of $500What effect will this discount have on each of the following characteristics of the resulting price distribution?

a. Shape

b. Median

c. Interquartile range (IQR)

Growth charts We used an online growth chart to find percentiles for the height and weight of a 16-year-old girl who is 66 inches tall and weighs 118 pounds. According to the chart, this girl is at the 48th percentile for weight and the 78th percentile for height. Explain what these values mean in plain English.

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.
