Given Data:
x and y are related by 2x-3y-7=0
Mean of x = 1
Mean deviation of x = 0.3
Calculating Mean Deviation of y:
To calculate the mean deviation of y about its mean, we first need to find the mean of y.
Finding the Mean of y:
From the given relation 2x-3y-7=0, we can rewrite it as:
y = (2x - 7) / 3
Given that the mean of x is 1, substituting this into the equation, we get:
y = (2(1) - 7) / 3
y = -5/3
So, the mean of y is -5/3.
Calculating the Mean Deviation of y:
Mean deviation of y about its mean = |y - mean of y|
Mean deviation of y = |-5/3 - (-5/3)| = 0
Therefore, the mean deviation of y about its mean is 0.
Coefficient of Mean Deviation of y:
The coefficient of mean deviation is given by:
Coefficient of mean deviation = Mean deviation of y / Mean of y
Substitute the values we found:
Coefficient of mean deviation = 0 / (-5/3) = 0
Conclusion:
The coefficient of mean deviation of y about its mean is 0.
