Answer:
approximately 54.7% did not respond.
Step-by-step explanation:
Consider the provided information.
The college chooses 150 businesses at random from telephone listings.
Of these, 68 return the questionnaire.
That means 68 of them responded.
The number of people who did not respond are:
150-68=82
The number of people who did not respond are 82.
Now find the percentage of people who did not respond.
Hence, approximately 54.7% did not respond.
