Question

Suppose that the mean of the sampling distribution for the difference in two sample means is 0.

Answer 1

Answer:

Optin b is right

Step-by-step explanation:

given that the  mean of the sampling distribution for the difference in two sample means is 0.

This means that when two sample means are equal we get difference is 0 and this would be the point estimate of mean for differene of means distribution.

Hence the four options given can be analysed

. the two sample means are both 0.   -- False need not be 0 but equal

B. the two sample means are equal to each other.   -- True

C. the two population means are both 0.  -- False need not be 0

D. the two population means are equal to each oth  -- False only sample means are 0 and if sample represents population this may be 0
