The prediction of the editor is not correct
Step-by-step explanation:
Step 1 :
Given,
Percentage of email that comes back undelivered = 3%
Number of email the editor sends out = 12181
Number of email predicted by the editor which is undelivered = 433
Step 2 :
To compute the actual number of emails undelivered we need to compute 3% of the emails that is actually sent.
= 3% of 12181 = 0.03 * 12181 = 365.43 which is 366 rounded to the closest integer.
Step 3:
Hence we can conclude that the prediction of the editor is not correct as only 366 undelivered notices are received back as against his prediction of 433 notices.
