Assuming she is consistent
The answer: it is not in a quadrant, true
Answer
A. 129.3
B. The students ages can be any number within the ranges, so having the middle number wont represent the other possible heights.
Step by step
'h' is the number between the surrounding number, the first would be 122.
You need to multiply the hight by frequency of each one,
122x7 =854
126x8=1008
130x13=1690
134x9=1206
138x3=414
Add them up = 5172
5172/40 =129.3
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."
