The following data give the number of television sets owned by 40 randomly selected households. $$ \begin{array}{rrrrrrrrrr} 1 & 1 & 2 & 3 & 2 & 4 & 1 & 3 & 2 & 1 \\ 3 & 0 & 2 & 1 & 2 & 3 & 2 & 3 & 2 & 2 \\ 1 & 2 & 1 & 1 & 1 & 3 & 1 & 1 & 1 & 2 \\ 2 & 4 & 2 & 3 & 1 & 3 & 1 & 2 & 2 & 4 \end{array} $$ a. Prepare a frequency distribution table for these data using single-valued classes. b. Compute the relative frequency and percentage distributions. c. Draw a bar graph for the frequency distribution. d. What percentage of the households own two or more television sets?

Step 1
To prepare a frequency distribution table using single-valued classes, we need to group the data into intervals. We can use intervals of 1, starting from 0 to 4. The frequency distribution table would look like: | Number of TV sets | Frequency Show more…

A researcher with A. C. Nielsen wanted to determine the number of televisions in households. He conducts a survey of 40 randomly selected households and obtains the following data. $$\begin{array}{cccccccc}1 & 1 & 4 & 2 & 3 & 3 & 5 & 1 \\\hline 1 & 2 & 2 & 4 & 1 & 1 & 0 & 3 \\\hline 1 & 2 & 2 & 1 & 3 & 1 & 1 & 3 \\\hline 2 & 3 & 2 & 2 & 1 & 2 & 3 & 2 \\ \hline 1 & 2 & 2 & 2 & 2 & 1 & 3 & 1 \\\hline\end{array}$$ (a) Are these data discrete or continuous? Explain. (b) Construct a frequency distribution of the data. (c) Construct a relative frequency distribution of the data. (d) What percentage of households in the survey have 3 televisions? (e) What percentage of households in the survey have 4 or more televisions? (f) Construct a frequency histogram of the data. (g) Construct a relative frequency histogram of the data. (h) Describe the shape of the distribution.
