Regression and Correlation
In regression calculation for five pairs of the observations one pair of values was lost when the data were filed. For regression of y on x the equation was calculated as
The four recorded pairs are as follows:
x y
0.1 0.1
0.2 0.3
0.4 0.7
0.3 0.4
Find the missing pair of values, using the following data for the four pairs above:
∑x=1,∑x²=0.3,∑xy=0.47,∑y=1.5.
Please anyone solve this question!
