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.
To find the relative frequency of people age 12-15 who had over 500 messages, we need to sum up the total number of people in that age range who had over 500 messages.
From the table, we see that there were 78 people age 12-15 who had over 500 messages.
Next, we find the total number of people in the entire dataset who had over 500 messages:
24 people age 12-15
35 people age 16-19
67 people age 20-23
Adding these up, we get a total of 24 + 35 + 67 = 126 people who had over 500 messages.
Finally, we calculate the relative frequency by dividing the number of people age 12-15 who had over 500 messages (78) by the total number of people who had over 500 messages (126), and then multiplying by 100 to get a percentage:
(78 / 126) * 100 ≈ 61.9%
Therefore, the relative frequency of people age 12-15 who had over 500 messages is approximately 61.9%.
Incorrect
still incorrect
I apologize for the oversight. Let's correct the calculation:
The total number of people age 12-15 who had over 500 messages is 78.
The total number of people of all ages who had over 500 messages is the sum of all those categories: 78 (age 12-15), 97 (age 16-19), and 177 (age 20-23), which equals 78 + 97 + 177 = 352.
Now we can calculate the relative frequency for people age 12-15 who had over 500 messages:
(78 / 352) * 100 ≈ 22.2%
Therefore, the correct relative frequency of people age 12-15 who had over 500 messages is approximately 22.2%. Thank you for pointing out the error. Let me know if you need any further assistance.
I apologize for the error in my initial calculation. Let's correct that:
