For the following numerical attributes, state whether each is discrete or continuous. a. The number of insufficient-funds checks received by a grocery store during a given month b. The amount by which a 1-lb package of ground beef decreases in weight (because of moisture loss) before purchase c. The number of New York Yankees during a given year who will not play for the Yankees the next year d. The number of students in a class of 35 who have purchased a used copy of the textbook

Short Answer

Expert verified
a. Discrete, b. Continuous, c. Discrete, d. Discrete

Step by step solution

01

Analyze Attribute a

Analyze the question 'The number of insufficient-funds checks received by a grocery store during a given month'. The quantity in question involves counting the number of checks, which can only be whole numbers. Hence, this is a discrete attribute.
02

Analyze Attribute b

Analyze the question 'The amount by which a 1-lb package of ground beef decreases in weight (because of moisture loss) before purchase'. The quantity in question implies it can take any value within a certain range, from 0 to 1 lb, including decimal values. Hence, this is a continuous attribute.
03

Analyze Attribute c

Analyze the question 'The number of New York Yankees during a given year who will not play for the Yankees the next year'. The quantity in question involves counting the number of players, which can only be whole numbers. Hence, this is a discrete attribute.
04

Analyze Attribute d

Analyze the question 'The number of students in a class of 35 who have purchased a used copy of the textbook'. The quantity in question involves counting the number of students, which can only be whole numbers. Hence, this is a discrete attribute.

Representatives of the insurance industry wished to investigate the monetary loss resulting from earthquake damage to single-family dwellings in Northridge, California, in January 1994 . From the set of all single-family homes in Northridge, 100 homes were selected for inspection. Describe the population and sample for this problem.

A building contractor has a chance to buy an odd lot of 5000 used bricks at an auction. She is interested in determining the proportion of bricks in the lot that are cracked and therefore unusable for her current project, but she does not have enough time to inspect all 5000 bricks. Instead, she checks 100 bricks to determine whether each is cracked. Describe the population and sample for this problem.

"Ozzie and Harriet Don't Live Here Anymore" (San Luis Obispo Tribune, February 26,2002 ) is the title of an article that looked at the changing makeup of America's suburbs. The article states that nonfamily households (e.g. homes headed by a single professional or an elderly widow) now outnumber married couples with children in suburbs of the nation's largest metropolitan areas. The article goes on to state: In the nation's 102 largest metropolitan areas, "nonfamilies" comprised 29 percent of households in 2000 , up from 27 percent in 1990 . While the number of married-with-children homes grew too, the share did not keep pace. It declined from 28 percent to 27 percent. Married couples without children at home live in another 29 percent of suburban households. The remaining 15 percent are single-parent homes. Use the given information on type of household in 2000 to construct a frequency distribution and a bar chart. (Be careful to extract the 2000 percentages from the given information).

A 2005 AP-IPSOS poll found that \(21 \%\) of American adults surveyed said their child was heavier than doctors recommend. The reasons given as the most important contributing factor to the child's weight problem is summarized in the accompanying table. $$ \begin{array}{lr} \text { Lack of exercise } & 38 \% \\ \text { Easy access to junk food } & 23 \% \\ \text { Genetics } & 12 \% \\ \text { Eating unhealthy food } & 9 \% \\ \text { Medical condition } & 8 \% \\ \text { Overeating } & 7 \% \end{array} $$ a. Construct a bar chart for the data on the most important contributing factor. b. Do you think that it would be reasonable to combine some of these contributing factors into a single category? If so, which categories would you combine and why?

Based on a study of 2121 children between the ages of one and four, researchers at the Medical College of Wisconsin concluded that there was an association between iron deficiency and the length of time that a child is bottle-fed (Milwaukee Journal Sentinel, November 26, 2005). Describe the sample and the population of interest for this study.
