How often do we use our cell phone in public to catch up with family and friends? Results of a recent study conducted by the Pew Research Center of 3042 cell phone users are shown in Table 2-13. We'll make a circle graph to display these data. TABLE 2-13 Frequency of Cell Phone Use in Public to Catch Up with Family and Friends Number Fractional Part Percentage 894 29.4% 1161 38.2% 615 20.2% 372 Frequency Frequently Occasionally Rarely Never Total (a) Fill in the missing parts in Table 2-13 for "Never" Remember that the central angle of a circle is 360°. Round to the nearest degree. (b) Fill in the totals. What is the total number of re- sponses? Do the percentages total 100% (within rounding error)? Do the numbers of degrees total 360° (within rounding error)? 894/3042 1161/3042 615/3042 Number of Degrees 29.4% x 360° 106° 138⁰ 38.2% X 360° 20.2% X 360° 73° For "Never" Fractional Part = 372/3042; Percentage = 12.2%. Number of Degrees = 12.2% X 360° 44°. The symbol means "approximately equal." The total number of responses is 3042. The percentages total 100%. You must have such a total in order to create a circle graph. The numbers of degrees total 361°. This is within rounding error of 360°.

conducted by the Pew Research Center of 3042 cell phone users are shown in Table 2-13. We'll make a circle
graph to display these data.

Total
(a) Fill in the missing parts in Table 2-13 for "Never"
Remember that the central angle of a circle is
360°. Round to the nearest degree.
(b) Fill in the totals. What is the total number of re-
sponses? Do the percentages total 100% (within
rounding error)? Do the numbers of degrees total
360° (within rounding error)?
(c) Draw a circle graph. Divide the circle into pieces
with the designated numbers of degrees. Label
each piece, and show the percentage correspond-
ing to each piece. The numbers of degrees are
usually omitted from pie charts shown in newspa-
pers, magazines, journals, and reports.

For "Never" Fractional Part 372/3042;
Percentage = 12.2%. Number of Degrees =
12.2% X 360° 44°. The symbol means
"approximately equal."
Rarely
20.2%
The total number of responses is 3042. The
percentages total 100%. You must have such a total in
order to create a circle graph. The numbers of degrees
total 361°. This is within rounding error of 360°.
