number of films seen by a group of people during the past year
No of films seen 0 1 2 3 4 5 6 7 8
No of people 23 12 9 6 3 4 2 0 1
What percentage of people had seen more than 4 films during the year?
would it be 10/60 = 0.1666 x 100 = 16.6%
is this right???
It took me a while to understand your problem. I assume it means that 23 people saw 0 films, 12 saw 1 film, 9 saw 2 films, etc.
Only 7 people saw MORE than 4 films (10 saw more than 3 films)
Find the percentage for 7/60.
so would it be 7/60 = 0.12 x 100 = 11.67 so to 1 decimal place it would be 11.6% is this right?
You're right -- except in the rounding. 11.67 rounded to the nearest tenth is 11.7%,
was just wondering shouldnt it be 10 people that saw more then 4 films beacause: 3 people saw 4 films, 4 people saw 5 films, 2 people saw 6 films, 1 people saw 8 films and the total people that watched more then 4 films is 10 (3+4+2+1)
Sarah the three people who saw four films, did NOT see more than four films. 7 people saw MORE than four films.
If it meant "4 or more films," it would have stated that, right?
4 or more films = 10
more than 4 films = 7
Read your assignments carefully!
=)
Three people saw 4 films. Your question asks how many people saw more than 4 films.
oh right so i don't include the people who only saw 4 films. get it now thank you for your help.
You're very welcome.
so if i wanted to work out the mean number of films seen by these people in the year i would do the total amount of people which is 60 divided by the total value which is 10 so that is 60/10 ??
The mean is the average number of films seen by this group. If "these people" are those who saw more than 4 films, you'd add the total number of films seen (20 + 12 + 8) and divide by 7.
If you need the mean for all of the people, you'd add 12 + 18 + 18 + 12 + 20 + 12 + 8. Divide that sum by 60.
Hi
lol
To find the mean number of films seen by the entire group, you would add up the number of films seen by each person and then divide by the total number of people.
So, the calculations would be:
(0 x 23) + (1 x 12) + (2 x 9) + (3 x 6) + (4 x 3) + (5 x 4) + (6 x 2) + (7 x 0) + (8 x 1) / 60
Simplifying the calculation:
0 + 12 + 18 + 18 + 12 + 20 + 12 + 0 + 8 = 100
The mean number of films seen by the entire group would be 100/60, which is approximately 1.67 films.
