In this question, the data is given for the season and the actual demand.
00:04
We have to use the regression analysis.
00:09
Recreation analysis, we have to use this to find out the demand to forecast summer in 2013.
00:17
So it is given sum of x, this value is given to us, that is 376.
00:23
The sum of y is given to us, that is 3 ,709.
00:28
So now here the mean of x is given, mean of x that is equals to 4 .5 and the mean of y is equals to what? this is also given to us.
00:38
So mean of y that is equals to 463 .6 .6 to 5.
00:43
This is the mean of y.
00:45
Now, what will be the sum of square then? so sum of squares that is s -s -x that is equals to 42 and the sum of 3 .6.
00:58
Sum of products that is given by sb so this is equal to 3 ,854 .5.
01:09
So now if we write the regression equation, so the regression equation, this is represented by y cap, this is equals to b multiplied by capital x plus a...
