Chapter 2: Q. 34 (page 132)

Use the following information to answer the next six exercises. Sixty-five randomly selected car salespersons were asked the number of cars they generally sell in one week. Fourteen people answered that they generally sell three cars; nineteen generally sell four cars; twelve generally sell five cars; nine generally sell six cars; eleven generally sell seven cars.

First quartile = _______

Short Answer

Expert verified

We get Q1=4. So 4is the first quartile.

Step by step solution

01

Given information

From Sixty-five car salespersons, fourteen people answered that they sell three cars; nineteen generally sell four cars; twelve generally sell five cars; nine generally sell six cars; eleven generally sell seven cars in one week.

02

Explanation

According to the given information, the data is

33333333333333444444444444444444455555555555566666666677777777777

Here we divide all these 65data on a 100scale. We asked to find the find quartile of the number of cars sold which is the first 25%of the data. Hence we get 25%of the data from the first is 4.

Construct a box plot of the data.

The population in Park City is made up of children, working-age adults, and retirees. Table 2.10shows the three age groups, the number of people in the town from each age group, and the proportion (%) of people in each age group. Construct a bar graph showing the proportions.

Use the following information to answer the next nine exercises: The population parameters below describe the full-time equivalent number of students (FTES) each year at Lake Tahoe Community College from 1976鈥�1977 through 2004鈥�2005.

鈥� 渭 = 1000 FTES

鈥� median = 1,014 FTES

鈥� 蟽 = 474 FTES

鈥� first quartile = 528.5 FTES

鈥� third quartile = 1,447.5 FTES

鈥� n = 29 years

Compare the IQR for the FTES for 1976鈥�77 through 2004鈥�2005 with the IQR for the FTES for 2005-2006 through 2010鈥�2011. Why do you suppose the IQRs are so different?

The following data sets list full time police per 100,000citizens along with homicides per 100,000citizens for the city of Detroit, Michigan during the period from 1961to1973.

a. Construct a double time series graph using a common x-axis for both sets of data.

b. Which variable increased the fastest? Explain.

Use the following information to answer the next two exercises. Sixty-five randomly selected car salespersons were asked the number of cars they generally sell in one week. Fourteen people answered that they generally sell three cars; nineteen generally sell four cars; twelve generally sell five cars; nine generally sell six cars; eleven generally sell seven cars.

Looking at your box plot, does it appear that the data are concentrated together, spread out evenly, or concentrated in some areas, but not in others? How can you tell?
