Hello, let's have a look on the question.
00:02
So here we calculated these values using excel.
00:05
So x bar here is equal to summation of xi divided by n, and summation of xi is 100 and n is given to us 5.
00:12
So this value will be equal to 20.
00:14
Next we have y bar, that is summation of yi divided by n, which is equal to 885 divided by 5, that is 177.
00:24
Next we have sxx, that is, summation of xi minus y, whole square.
00:30
This is xi minus x bar whole square, which is equal to 350.
00:37
Next we have s of yy, which is summation of yi minus y bar whole square, that is 15318...
