Answer:
Mean = 30.9
Range = 80
Interquartile Range = 36
Step-by-step explanation:
The mean of a set of numbers is the sum divided by the number of terms. In other words that means 2, 22, 4, 36, 82, 44, 65, 30, 8, 16 go over a fraction like this. There are 10 numbers here so this is our denominator.
For the range, all we do is subtract the minimum value from the maximum which is 82 - 2. That gives us 80.
For the IQ Range....
Arrange the terms in ascending order.
2, 4, 8, 16, 22, 30, 36, 44, 65, 82
Then we need to find the median which is the average of the two middle terms.
So for the lower half of data 2, 4, 8, 16, 22 we have the median of 8
And for the upper half 30, 36, 44, 65, 82 we have the median of 44.
To find the IQ Range it is the difference between the first quartile (8) and the third (44)
So 44 - 8 = 36
So easy
so driscoll has 9 reports to grade and each page has 6 pages.
just multiply 9 and 6 which gives you your answer 54.
so out of 54, he has graded only 12 pages which means that you need to subtract.
driscoll has 42 pages left to grade.
you can recheck your answer by adding 42 ans 12 which gives your answer as 54. so yup our answer is right.
