Use the table to answer the question
Number of text messages
0-200. 201-500. Over 500
Age 12-15. 24. 47. 78
16-19. 20. 35. 97
20-23 55. 67. 177
Given the date and the table about the number of text messages per day, what is the relative frequency of the people 12 to 15 who have over 500 messages round the percentage to the nearest 10th
To find the relative frequency of people aged 12-15 who have over 500 messages, we need to add up the total number of people aged 12-15 and then find the proportion that have over 500 messages.
Total number of people aged 12-15 = 24 + 47 + 78 = 149
Number of people aged 12-15 with over 500 messages = 78
Relative frequency = (Number of people aged 12-15 with over 500 messages) / (Total number of people aged 12-15)
Relative frequency = 78 / 149
Relative frequency = 0.5235
To convert this to a percentage, we multiply by 100:
Relative frequency = 52.35%
Rounded to the nearest tenth, the relative frequency of people aged 12-15 who have over 500 messages is 52.4%.
