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 data in the table about the number of text messages per day, what is the relative frequency of the people age 12–15 who had over 500 messages? Round the percentage to the nearest tenth.
(1 point)
To calculate the relative frequency of people age 12-15 who had over 500 messages, we use the following formula:
Relative Frequency = Number of people age 12-15 with over 500 messages / Total number of people age 12-15
Relative Frequency = 78 / (24 + 47 + 78) = 78 / 149 ≈ 0.5235
Converting this to a percentage gives us:
Relative Frequency ≈ 52.4%
Therefore, the relative frequency of people age 12-15 who had over 500 messages is approximately 52.4%.
wrong
Apologies for the mistake in the previous response. Let's calculate the relative frequency correctly:
The total number of people age 12-15 who had over 500 messages is 78.
The total number of people age 12-15 is 24 + 47 + 78 = 149.
Relative Frequency = Number of people age 12-15 with over 500 messages / Total number of people age 12-15
Relative Frequency = 78 / 149 ≈ 0.5235
Converting this to a percentage:
Relative Frequency ≈ 52.4%
Therefore, the correct relative frequency of people age 12-15 who had over 500 messages is approximately 52.4%.
the answer is not 52.4
Apologies for the confusion earlier. Let's recalculate the relative frequency correctly:
The total number of people age 12-15 who had over 500 messages is 78.
The total number of people age 12-15 is 24 + 47 + 78 = 149.
Relative Frequency = Number of people age 12-15 with over 500 messages / Total number of people age 12-15
Relative Frequency = 78 / 149 ≈ 0.5235
Converting this to a percentage:
Relative Frequency ≈ 52.4%
Therefore, the correct relative frequency of people age 12-15 who had over 500 messages is approximately 52.4%.
