1. State whether the following statements are true or false and also give the reason in support of your answer:
(2×5=10)
a) The total number of all possible samples of size 2 without replacement from a population of size 7 is 49.
b) RBD is suitable in situations where it is not possible to divide the experimental material into a number of homogeneous blocks.
c) If experimental error is reduced considerably and the efficiency of the design is decreased.
d) If strata are heterogeneous then stratified sampling schemes provides estimates with greater precision.
e) As we increase the sample size, representativeness of the population by the sample decreases.
2. (a) Draw all possible samples of size 2 from the population [2, 3, 4] and verify that E(X) = X Also find variance of X.
(b) A sample of 60 students is to be drawn from a population consisting of 600 students belonging to two villages, A and B. The means and standard deviations of their marks are give below:
