Answer:
Hence MAD=0.8
Step-by-step explanation:
<u>MAD-</u>
MAD is also known as Mean Absolute Deviation.
We find MAD by the following steps:
- Firstly we find the mean of the data
- Then we subtract each entry from the mean to obtain the deviation
- Then find the absolute value of the deviation which is also known as absolute deviation.
- Finally we find the mean of the absolute deviation.
Now we are given a table of the absolute deviation we just need to calculate the mean of the absolute deviation.
The absolute deviation is given as:
1 3 1 0 0 1 0 0 1 1
The mean of this is calculated as:
Hence, MAD=0.8
Answer:
=NORM.INV(0.17,98,15)
Step-by-step explanation:
Consider X represents the IQs of sample participants.
Then X follows the Normal Distribution with mean 98 and standard deviation 15.
That is,
The probability value is 17th percentile (that is 0.17)
To find the value of X using Excel, the<em> Inverse Normal Distribution </em>is used.
The Excel function =NORM.INV(0.22,105,17) is used to find the IQs of sample participants.
