Answer:
448 subscribers
Step-by-step explanation:
Given:
Number of randomly selected customers = 50
Out of 50 users, number using internet for more than 15 hours per week = 28
Now, number of subscribers = 800
Let the number of subscribers using internet for more than 16 hours per week be 'x'.
So, <em>out of 50 subscribers, 28 use internet for more than 15 hours</em>
Therefore<em>, out of 800 subscribers, 'x' use internet for more than 15 hours.</em>
Setting up a proportion and solving by cross multiplication method, we get:
Therefore, the number of subscribers using internet for more than 15 hours a week is 448 out of total 800 subscribers.
