How to do part(ii) ? In the solution, some delta concept is being used. What is this delta? How are they calculating this delta?? Please help.
This Delta is the variance of the sample data. The test statistic used while checking for equality of variances is variance of x/variance of y, where x and y are the sample data
Ok. But I am getting different variances for dataset A and dataset B using formula of variance s^2 = (1/n-1)*(summation of x^2 - n*x-bar^2) Using this, s(A)^2 is coming 3.69643 and s(B)^2 is coming 2.4107. Right???
Sorry, now I got it. Now I just fed the data sets in calculator and found sx and sy, and squared them. Thanks!
