Sixty people were asked how many films they had seen in the past year. The results are shown in table 1.
Table 1: number of films seen by a group of people during the past year
No of film seen(x)0 1 2 3 4 5 6 7 8
N0 of people(f) 23 12 9 6 3 4 2 0 1
What percentage of people had seen more than 4 films during the year?
Give your answer correct to 1 decimal place.
add the number of people seeing four, five, six, seven, and eight films.
Divide by the total number of people in the group.
Multiply by 100.
To find the percentage of people who have seen more than 4 films during the year, follow these steps:
1. Add the number of people who have seen four, five, six, seven, and eight films in Table 1. These are the values in the "No of people(f)" column for those corresponding film numbers.
Add the following values: 3 + 4 + 2 + 0 + 1 = 10
2. Calculate the total number of people in the group by adding up all the values in the "No of people(f)" column of Table 1.
Add the following values: 23 + 12 + 9 + 6 + 3 + 4 + 2 + 0 + 1 = 60
3. Divide the total number of people who have seen more than 4 films (step 1) by the total number of people in the group (step 2).
10 / 60 = 0.1667
4. Multiply the result by 100 to convert it to a percentage.
0.1667 * 100 = 16.67
Therefore, the percentage of people who have seen more than 4 films during the year is 16.7% (rounded to one decimal place).
