Question 5

Refer to the following breakdown of responses to a survey of room service in a hotel.  What type of chart should be used to describe the frequency table?
A)A pie chart
B)A bar chart
C)A histogram
D)A frequency polygon

Accepted Answer

A bar chart is the best choice to display frequency tables as it allows for clear comparison between categories and can easily show the most frequent and least frequent responses. A pie chart would not be appropriate since there are too many categories to display effectively in a circular format. A histogram is used for continuous data, and a frequency polygon is used to plot continuous data points.

Question 6

A pie chart shows the ______________________.
A)Relative frequencies of a qualitative variable
B)Relative frequencies of a quantitative variable
C)Frequencies of a nominal variable
D)Frequencies of a ratio variable

Accepted Answer

A pie chart is used to display the relative frequencies or proportions of categories of a qualitative variable. It is a circular chart that is divided into slices, with each slice representing a category or group and the size of each slice indicating the proportion or percentage of that group.

Question 7

Refer to the following breakdown of responses to a survey of "Are you concerned about being tracked while connected to the Internet?"  What type of chart should be used to describe the frequency table?
A)A pie chart
B)A bar chart
C)A histogram
D)A frequency polygon

Accepted Answer

A bar chart is the best choice to show the frequency table as it allows for easy comparison of the different response categories. A pie chart may not be the best choice as it can be difficult to distinguish between small differences in the proportions of each category. A histogram and a frequency polygon are typically used to show the distribution of continuous data, rather than the frequencies of categorical data.

Question 8

Refer to the following breakdown of responses to a survey of room service in a hotel.  What percent of the responses indicated that customers were satisfied?
A)40%
