A set of data has MAD O and one of the data values is 14. What can you say about the data values?
1 answer:
Given:
Mean absolute deviation (MAD) = 0
One of the data values = 14.
To find:
The statement for other data values.
Solution:
We know that Mean absolute deviation (MAD) represents the average of absolute difference between observations and mean.
MAD is 0. It is possible if . It means all the values of
are 0.
It means no deviations in mean angle values and all the values are the same.
Therefore, if MAD is 0 and one data value is 14, then all the data values are same, i.e., 14.

<h3>How to determine the critical values corresponding to a 0.01 significance level?</h3>The scatter plot of the election is added as an attachment
From the scatter plot, we have the following highlights
- Number of paired observations, n = 8
- Significance level = 0.01
Start by calculating the degrees of freedom (df) using
df =n - 2
Substitute the known values in the above equation
df = 8 - 2
Evaluate the difference
df = 6
Using the critical value table;
At a degree of freedom of 6 and significance level of 0.01, the critical value is
z = 0.834
From the list of given options, 0.834 is between -0.881 and 0.881
Hence, the critical values corresponding to a 0.01 significance level used to test the null hypothesis of ρs = 0 is (a) -0.881 and 0.881
