Answer: Add all the absolute deviations and divide by number of swimmers.
Step-by-step explanation:
To find the mean absolute deviation of any data we need to follow the following steps:
- Start by finding the mean of the data set.
- Find the absolute value of the difference between each data value and the mean.
- Find the sum of the absolute values of the differences.
- Divide the sum of the absolute values of the differences by the number of data values.
We can see in the picture that it already dome with first two steps so the step after that is " Add all the absolute deviations and divide by number of swimmers."
Calculate 16% of 850.
The way I do this is by breaking it up into smaller pieces.
First I would find 10% of 850. To do this I need to divide 850 by 10, as 100%/10 gives us 10%, which is what we need.
So 10% = 85
Then we need 5%, which is half of 10%, therefore half of 85,
So 5% = 42.5
Then we need 1% which is 10%/10, so 85/10.
So 1% = 8.5
Then we add all these together to get 16%.
So 16% = 136
They predict that 102 people will come back, which is less than the 16% that should come back to stay again, so their prediction is too low.
