Some of the table values are purposely missing.What was the frequency of the "Don't Know" responses?

This stem-and-leaf plot shows the lengths of reigns (in years) of the British monarchs.The shape of this plot is best described as:

A particular advantage of a stem-and-leaf plot over a histogram or bar chart is that:

Two statistics students are arguing over which type of bar graph to use.One insists that a bar graph that displays the relative frequency will be better for displaying the overall shape of the data.The other holds that only a frequency bar graph will suffice.You happen along and hear their conversation.What advice do you give them?

What data value is represented by the bold and underlined "0" in the stem-and-leaf diagram? (Note: It is bold and underlined for emphasis only.)

Judging from this stem-and-leaf display, the data set appears to be:

What is the value of the data point represented by the bold and underlined "0" in the stem-and-leaf diagram? (Note: It is bold and underlined for emphasis only.)

This stem-and-leaf plot shows the lengths of reigns (in years) of the British monarchs.According to the plot, how many British rulers had reigns that lasted less than a full year?

Relative frequency is best suited to describing __________________ data.

This stem-and-leaf plot shows the lengths of reigns (in years) of the British monarchs.According to the plot, how many British rulers had reigns that lasted 32 years?

A student counted the number of candies of each color in a bag of 57 Reese's Pieces.The results are shown in the bar graph. How many of the candies were colored orange?

The shape of the data set summarized in the stem-and-leaf diagram is best described as:

A student counted the number of candies of each color in a bag of 57 Reese's Pieces.The results are shown in the bar graph. What percentage of the candies were not colored orange?

A numeric data set is __________________ if the set of all possible values is any number within an interval of numbers.

Concerning qualitative data, the ______________ of a particular class is the frequency of the class divided by the total number of observations.

If there are more than two observations on the same person, the data set is:

What data value is represented by the bold and underlined "1" in the stem-and-leaf diagram? (Note: It is bold and underlined for emphasis only.)

A numerical data set is ___________ if the set of all possible values is finite, or countably infinite.

This histogram shows the age at which 548 patients were first diagnosed with diabetes.The shape of this histogram is best described as:

Concerning qualitative data, the _____________ of a particular class is the count for that class.
