Chapter 1: Q. T1.1. (page 86)

1 You record the age, marital status, and earned income of a sample of 1463 women. The number and type of variables you have recorded are

a. 3 quantitative, 0 categorical.

b. 4 quantitative, 0 categorical.

c. 3 quantitative, 1 categorical.

d. 2 quantitative, 1 categorical.

e. 1 quantitative, 2 categorical.

Short Answer

Expert verified

The correct option (d)

d. 2 quantitative, 1 categorical.

Step by step solution

01

Step 1. Given information

The number and type of variables you have recorded are

a. 3 quantitative, 0 categorical.

b. 4 quantitative, 0 categorical.

c. 3 quantitative, 1 categorical.

d. 2 quantitative, 1 categorical.

e. 1 quantitative, 2 categorical.

02

Step 2. The best option.

The topics investigated are the variables.

Age, marital status, and earned income are variables.

Categorical/qualitative variables categorise individuals, whereas quantitative variables are numerical variables.

Age is a quantitative variable because it has numerical values (such as 24 years).

Because the categories are Single, Married, Divorced, Widowed, and so on, marital status is a categorical variable.

Earned income is a quantitative variable because it has numerical values (such as 3000 dollars).

We then notice that there are two quantitative variables (age and earned income) as well as one categorical variable (earned income).

As a result:

d. 2 quantitative, 1 categorical.

The Dallas Mavericks won the NBA championship in the 2010–2011 season. The two-way table displays the relationship between the outcome of each game in the regular season and whether the Mavericks scored at least 100 points.

Which of the following is the best evidence that there is an association between the outcome of a game and whether or not the Mavericks scored at least 100 points?

(a) The Mavericks won 57 games and lost only 25 games.

(b) The Mavericks scored at least 100 points in 47 games and fewer than 100 points in only 35 games.

(c) The Mavericks won 43 games when scoring at least 100 points and only 14 games when scoring fewer than 100 points.

(d) The Mavericks won a higher proportion of games when scoring at least 100 points (43/47) than when they scored fewer than 100 points (14/35).

(e) The combination of scoring 100 or more points and winning the game occurred more often (43 times) than any other combination of outcomes.

Pulse rates Refer to Exercise 88.

(a) Find the range of the pulse rates for all 19 students and the range of the pulse rates excluding the student with the medical issue.

(b) Explain what part (a) suggests about using the range as a measure of variability for a distribution of quantitative data.

Superpower Refer to Exercise 24.

(a) Find the distribution of superpower preference for the students in the sample from each country (i.e., the United States and the United Kingdom). Make a segmented bar graph to compare these distributions.

(b) Describe what the graph in part (a) reveals about the association between country of origin and superpower preference for the students in the sample.

Who buys cars? A car dealer keeps records on car buyers for future marketing purposes. The table gives information on the last 4 buyers.

Part (a). Identify the individuals in this data set.

Part (b). What variables were measured? Classify each as categorical or quantitative.

(a) Identify the individuals in this data set.

(b) Make a frequency bar graph to display the data. Describe what you see.
