They should go on to launch the online edition

Step-by-step explanation:

Total surveyed = 400

A = accept if 15% above subscribes

B = reject if subscribers are less than 15%

on the survey it is clearly stated that 67 expressed interest.

lets get 16% of total survey

= 15% x 400

= 60.

Since number of subscribers that showed interest is greater than number 15%

Hence the company can go ahead to launch the online edition

Accept A
