Question

The number of hours of television programme watched on Sunday in 40 houses were as follows
9 5 4 3 4 4 9 9 8 9
9 5 10 9 10 10 10 4 9 6
7 9 5 9 9 8 6 7 9 6
6 5 9 9 8 7 8 10 10 9
1) Organise the following numbers in a tabular form.
2) Estimate the mean, median and mode of this distribution.
3) What is the range of the data?

Answer 1

1.

Have a table including the score, x (different hours) in order. Then include frequency (how many times that number of hour appears).

2.

The mean would be adding all the numbers then dividing it by 40 (total amount of houses). The median would be to organise the numbers from smallest to largest first. Then do 40/2 = 20, so find then find the 20th and 21st number then add them together and divide by 2. The mode is the number of hours that appears the most.

3.

The range is the biggest number minus the smallest number.

Answer 2

Answer:

frequency distribution table

Step-by-step explanation:

Mean

Apply formula first to get answer.

mean= Sum of observations /total number of observations.

=302/40

=151/20

and =151/20
