Chapter 3: Problem 61

An article in the San Luis Obispo Tribune (November 20,2002 ) stated that \(39 \%\) of those with critical housing needs (those who pay more than half their income for housing) lived in urban areas, \(42 \%\) lived in suburban areas, and the rest lived in rural areas. Construct a pie chart that shows the distribution of type of residential area (urban, suburban, or rural) for those with critical housing needs.

Short Answer

Expert verified
The pie chart should have three sections representing urban, suburban, and rural areas. The angles of the sections will be approximately \(140.4^\circ, 151.2^\circ, and 68.4^\circ\) respectively.

Step by step solution

01

Understanding the Data

It is stated that \(39 \%\) of those with critical housing needs live in urban areas and \(42 \%\) live in suburban areas.
02

Calculate the Percentage for Rural Areas

Since we know the percentage of those living in urban and suburban areas, we can calculate the percentage of those living in rural areas by subtracting these percentages from \(100 \%\). This gives us that \(100 \% - 39 \% - 42 \% = 19 \%\), thus \(19 \%\) live in rural areas.
03

Representing the Data on a Pie Chart

To represent this data on a pie chart, we need to convert the percentages into degrees. The entire pie chart represents \(100 \%\) or \(360^\circ\). Therefore, each \(1 \%\) represents \(360^\circ / 100 = 3.6^\circ\). This means that urban areas will be represented by \(39 \% * 3.6 ^\circ = 140.4^\circ\), suburban areas will be represented by \(42 \% * 3.6^\circ = 151.2^\circ\), and rural areas will be represented by \(19 \% * 3.6^\circ = 68.4^\circ\). Make sure that when added together, these results sum up to \(360^\circ\). Draw a circle and divide it into three sections with angles of \(140.4^\circ, 151.2^\circ\) and \(68.4^\circ\) respectively, and label each with corresponding residential area and percentage.

The California Healthy Kids Survey in 1999 and 2001 asked 7 th, 9 th, and 1 1th graders in San Luis Obispo County whether they smoked tobacco. In \(1999,6 \%\) of 7 th graders, \(17 \%\) of 9 th graders, and \(23 \%\) of 11 th graders admitted smoking tobacco while in 2001 the corresponding figures were \(3 \%, 13 \%\), and \(22 \%\). Create a comparative bar chart showing bars for 7 th graders together, bars for 9 th graders together, and bars for 11 th graders together. Comment on any interesting features of the chart.

Each murder committed in Utah during the period \(1978-1990\) was categorized by day of the week, resulting in the following frequencies: Sunday, 109 ; Monday, 73 ; Tuesday, 97 ; Wednesday, 95 ; Thursday, 83 ; Friday, 107 ; Saturday, 100 . a. Construct the corresponding frequency distribution. b. What proportion of these murders was committed on a weekend day - that is, Friday, Saturday, or Sunday? c. Do these data suggest that a murder is more likely to be committed on some days than on other days? Explain your reasoning.

Poor fitness in adolescents and adults increases the risk of cardiovascular disease. In a study of 3110 adolescents and 2205 adults (Journal of the American Medical Association, December 21,2005 ), researchers found \(33.6 \%\) of adolescents and \(13.9 \%\) of adults were unfit; the percentage was similar in adolescent males \((32.9 \%)\) and females \((34.4 \%)\), but was higher in adult females \((16.2 \%)\) than in adult males ( \(11.8 \%\) ). a. Summarize this information using a comparative bar graph that shows differences between males and females within the two different age groups. b. Comment on the interesting features of your graphical display.

An exam is given to students in an introductory statistics course. What is likely to be true of the shape of the histogram of scores if: a. the exam is quite easy? b. the exam is quite difficult? c. half the students in the class have had calculus, the other half have had no prior college math courses, and the exam emphasizes mathematical manipulation? Explain your reasoning in each case.

The article "Determination of Most Representative Subdivision" (Journal of Energy Engineering [1993]: 43 - 55) gave data on various characteristics of subdivisions that could be used in deciding whether to provide electrical power using overhead lines or underground lines. Data on the variable \(x=\) total length of streets within a subdivision are as follows: \(\begin{array}{rrrrrrrr}1280 & 5320 & 4390 & 2100 & 1240 & 3060 & 4770 & 1050 \\\ 360 & 3330 & 3380 & 340 & 1000 & 960 & 1320 & 530 \\ 3350 & 540 & 3870 & 1250 & 2400 & 960 & 1120 & 2120 \\ 450 & 2250 & 2320 & 2400 & 3150 & 5700 & 5220 & 500 \\ 1850 & 2460 & 5850 & 2700 & 2730 & 1670 & 100 & 5770 \\ 3150 & 1890 & 510 & 240 & 396 & 1419 & 2109 & \end{array}\) a. Construct a stem-and-leaf display for these data using the thousands digit as the stem. Comment on the various features of the display. b. Construct a histogram using class boundaries of 0 to 1000,1000 to 2000 , and so on. How would you describe the shape of the histogram? c. What proportion of subdivisions has total length less than 2000 ? between 2000 and 4000 ?
