1.- A sample of n = 6 elements from a large population shows the following results for a random variable X: -3 -2 -1 1 2 3 Find the following statistics: 3) x7 = O b} C11 2.25 c} 0.2 = 0 d} 0.3 = 2.25 e) 52:5.6 f)s= 2.3664 g) lfY=X+4, then s2 forYis=5.6 h) If the population is not very large: N = 50, what adjustment should be done to the sample variance of X? Answer: the formula is: and the aaiusted value of s2 for X is
