Deceptive Graphs. In Exercises 17鈥20, identify how the graph is deceptive.

Cost of Giving Birth According to the Agency for Healthcare Research and Quality Healthcare Cost and Utilization Project, the typical cost of a C-section baby delivery is \(4500, and the typical cost of a vaginal delivery is \)2600. See the following illustration.

Short Answer

Expert verified

The actual cost difference is less than twice between two deliveries, but the pictures for the two categories create a misleading inference of difference due to the use of 3-dimensional images.

Thus, the depiction is deceiving and makes the reader believe that C-section delivery is extremely expensive compared to vaginal delivery.

Step by step solution

01

Given information

A pictograph states the cost of a C-section equal to $4500 and the cost of a vaginal delivery equal to $2600 using a large milk bottle and a small milk bottle, respectively.

02

Describe a deceptive graph

A graph is said to be deceptive when it shows misleading results when compared to the actual scenario.

The deceptive feature of the graph can be identified by a comparison of the results with true data.

03

Identify the feature of a deceptive graph

The results state that the cost of a C-section is equal to $4500 and the cost of a vaginal delivery is equal to $2600.

By observing the graph, the difference between the costs of the C-section delivery and vaginal delivery appears to be greater than five times when the actual difference is approximately twice.

Moreover, the cost is a one-dimensional quantity, whereas the milk bottle is a three-dimensional figure. In other words, the graph is a 3-dimensional one, and the volume of the larger milk bottle is far greater than the volume of the smaller bottle.

Thus, the two milk bottles create a deceptive belief in the minds of the readers about the difference in the costs of the two types of deliveries.

Data Type

a. The listed playing times are all rounded to the nearest whole number. Before rounding, are the exact playing times discrete data or continuous data?

b. For the listed times, are the data categorical or quantitative?

c. Identify the level of measurement of the listed times: nominal, ordinal, interval, or ratio.

d. Which of the following best describes the sample data: voluntary response sample, random sample, convenience sample, simple sample?

e. The listed total game times are from one recent year, and the data are available for all years back to 1950. Given that the listed times are part of a larger collection of times, do the data constitute a sample or a population?

Constructing Frequency Distributions. In Exercises 11鈥18, use the indicated data to construct the frequency distribution. (The data for Exercises 13鈥16 can be downloaded at TriolaStats.com.)

Old Faithful Listed below are sorted duration times (seconds) of eruptions of the Old Faithful geyser in Yellowstone National Park. Use these times to construct a frequency distribution. Use a class width of 25 seconds and begin with a lower class limit of 125 seconds.

Stemplots. In Exercises 7 and 8, construct the stem plot.

Diastolic Blood Pressure Refer to the data listed in Exercise 6. Identify the two values that are closest to the middle when the data are sorted in order from lowest to highest. (These values are often used to find the median, which is defined in Section 3-1.)

Linear Correlation Coefficient In Exercises 9鈥12, the linear correlation coefficient r is provided. Use Table 2-11 on page 71 to find the critical values of r. Based on a comparison of the linear correlation coefficient r and the critical values, what do you conclude about a linear correlation?

Using the data from Exercise 7 鈥淐ar Weight and Fuel Consumption,鈥 the linear correlation coefficient is r = -0.987.

Scatterplot. In Exercises 5鈥8, use the sample data to construct a scatterplot. Use the first variable for the x-axis. Based on the scatterplot, what do you conclude about a linear correlation?
