An internet company Randomly selected 50 of his customers and ask them how many hours per week to use the Internet of those surveyed 28 use the Internet more than 15 hours per week based on the data if the company has 800 subscribers how many use more than 15 hours per week

448 subscribers use more than 15 hours per week

Step-by-step explanation:

In this question, we shall be using the proportion of what was gotten from a survey to estimate the number of subscribers that use more than 15 hours per week

From the question, we can see that out of the 50 people surveyed, 28 use more than 15-hours per week based on data

The proportion that thus use 15-hours per week based on data is 28/50

Now to know the number of subscribers out of 800 that use more than 15-hours per week based on data we have ; 28/50 * 800 = 28 * 16 = 448 subscribers
