In emails to monthly readers of a newsletter 3% of the emails come back undelivered
The editor predicts that if he sends out 12181 emails, he will receive 433 notices for
undelivered email. Do you agree with his prediction? Explain your rationale. Round to
the nearest integer, if necessary.

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.
