For two data sets, each with size 5, the variances are given to be 3 and 4 and the corresponding means are given 2 and 4, respectively. The variance of the combined data set is

For two data sets, each of size 5, the variances are given to be 4 and 5 and the corresponding means are given to be 2 and 4, respectively. The variance of the combined data set is :

For two data sets, each of size 5, the variances are given to be 4 and 5 and the corresponding means are given to be 2 and 4, respectively. The variance of the combined data set is (1) (11)/2 (2) 2 (3) (13)/2 (4) 5/2

For two data sets,each of size 5, the variances are given to be 4 and 5 and the corresponding means are given to be 2 and 4, respectively. The variance of the combined data set is (1) (11)/(2) (2) 2 (3) (13)/(2) (4) (5)/(2)

For two data sets, each of size 5, the variances are given to be 4 and 5 and the corresponding means are given to be 2 and 4, respectively. The variance of the combined data set is (1) (11)/2 (2) 2 (3) (13)/2 (4) 5/2

For two data sets, each of size 5, the variances are given to be 4 and 5 and the corresponding means are given to be 2 and 4, respectively. The variance of the combined data set is (1) (11)/2 (2) 2 (3) (13)/2 (4) 5/2

For two data sets , each of size 5, the variances are given to be 4 and 5 and the correcponding means are given to be 2 and 4, respectively . The variance of the combined data set is

For two data sets each of size 5 the variances are given by 4 and 5 and the corresponding means are given to be 2 and 4 respectively. Then find the variance of the combined data.
