,
We have to calculate the following terms
a)
b)
c)
d)
= Standard deviation
(Since there are more than 4 parts i will answer first 4, i.e. 4 : a,b,c,d)
(note in part d there are 2 value sd1 and sd2 because SD is calculated for each individual group and not combined)
P.S. (please upvote for my hard work)
