Answer 1

The mean number of newspapers bought by each person in Grace's survey is 2. This was calculated by multiplying the number of newspapers by their frequency, summing them up, and dividing by the total number of people surveyed.

Step-by-step explanation:

To calculate the mean number of newspapers bought by each person in Grace's survey, we need to multiply the number of newspapers by their corresponding frequency and then divide by the total number of persons surveyed. Using the information given:

• 0 newspapers × 4 people = 0
• 2 newspapers × 3 people = 6
• 3 newspapers × 8 people = 24

Now, add these products together to get the total number of newspapers bought by the group:

0 + 6 + 24 = 30 newspapers

Next, find the sum of the number of people surveyed:

4 + 3 + 8 = 15 people

Finally, divide the total number of newspapers by the total number of people to find the mean:

Mean = Total Newspapers / Total People

Mean = 30 newspapers / 15 people = 2 newspapers

So, the mean number of newspapers bought by each person is 2.
