Please answer part c, show work. Please be right. Thx.
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 894 1161 615 372 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)? (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. 894/3042 1161/3042 615/3042 Percentage 29.4% 38.2% 20.2% 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°. FIGURE 2-13 Frequency of Public Cell Phone Use to Catch Up with Family and Friends Never 12.2% 44° Number of Degrees 29.4% X 360° 38.2% X 360° 20.2% X 360° 73° 138° 106° Frequently 29.4% 106° 138° 73° Occasionally 38.2% Copyright 2019 Cengage Learning.
