To find the percent error in their prediction, we first calculate the difference between the predicted and actual number of attendees:
275 - 265 = 10
Then, we divide the difference by the predicted number of attendees and multiply by 100 to get the percent:
(10 / 275) * 100 = 3.63%
Therefore, the correct answer is 3.63%.
To calculate the percent error in their prediction, we need to find the difference between the predicted value and the actual value.
The predicted value is 275 and the actual value is 265.
The difference is 275 - 265 = 10.
To calculate the percent error, we divide the difference by the actual value and multiply by 100.
Percent error = (10 / 265) * 100 ≈ 3.77%
So, the correct answer is 3.77%.
To calculate the percent error, you need to find the difference between the predicted value and the actual value, divide it by the actual value, and then multiply by 100 to get the percentage.
In this case, the predicted value is 275 (the number of invitations mailed) and the actual value is 265 (the number of people who committed to attending).
First, find the difference: 275 - 265 = 10
Next, divide the difference by the actual value: 10 / 265 = 0.0377
Finally, multiply by 100 to get the percentage: 0.0377 * 100 = 3.77%
Therefore, the percent error in their prediction is 3.77%.
