A group of 6 students was asked, "How many hours did you watch television last week?" Here are their responses: 19, 9, 18, 16, 14, 19 Find the mean and median number of hours for these students.

Mean =          15.83 hours

Median =  17 hours

Step-by-step explanation:

The first step to follow when dealing with data distributions is to arrange the data in either an ascending or descending order.

Once this is done, we have the responses as

responses: 9. 14, 16, 18, 19, 19

The mean of the distribution can be obtained by dividing the total sum of the values, by the number of respondents.

this is

The mean of the distribution is 15.83 hours

The median is obtained by picking out the middle number of the distribution.  However, our distribution is even, and hence has two middle numbers. To solve this , we simply add the two numbers and divide by 2

= (16 + 18 )/2 = 34/2 =17

step-by-step explanation:

if the four friends split the cost, p, of the pizza evenly, then each friend pays one-fourth of the cost of the pizza.
