Question

ene n GUIDED EXERCISE 3 CIRCLE GRAPH survey of 500 people (as reported in USA Today) are shown in Table 2-13. We'll make a circle graph to display these data. How long do we spend talking on the telephone after hours (at home after 5 P.M.)? The results from a recent TABLE 2-13 Time Spent on Home Telephone After 5 P.M. Time Less than 'h hour h hour to 1 hour More than 1 hour Number 296 83 121 Fractional Part 296/500 83/500 Percentage 59.2 16.6 Number of Degrees 59.2% x360° ~ 213° 16.6% x 360-60 Total For More than 1 hour, Fractional Part- 121/500 Fill in the missing parts in Table 2-13 for "More than 1 hour." Remember that the central angle of a circle is 360. Round to the nearest degree. a) Percentage 24.2%; Number of Degrees 24.2% x 360 87o. The symbol means approximately equal." ) Fill in the totals. What is the total number of re-The total number of responses is 500. The sponses? Do the percentages total 100% (within rounding error)? Do the number of degrees total 360° (within rounding error)? percentages total 100%. You must have such a total in order to create a circle graph. The number of degree total 360°. 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 number of degrees are usually omitted from pie charts shown in newspa- pers, magazines, journals, and reports ) FIGURE 2-13 Hours on Home Telephone After 5 P.M. Less than /2 hour 59.2% 213 87° More than 1 hour 24.2% 1/2 hour to 1 hour 16.6%

Answer 1

Completely filled table is given below:

Time	number	fractional part	percentage	number of degress
less than 1/2 hour	296	296/500	59.2	59.2%x360=213
1/2 hour to one hour	83	83/500	16.6	16.6x360=60
more than 1 hour	121	121/500	24.2	24.2x360=87
total	500		100	360

b)

Total number of response will be 500

Total percentage is also 100%

Total number of degrees is also 360 degree

c) Circle graph/pie chart is given below:
