Consider random samples of size 86 drawn from population A with proportion 0.42 and random samples of size 60 drawn from population B with proportion 0.16.

(a) Find the mean and standard error of the distribution of differences in sample proportions, p A - p B

mean =

standard error=

(b) Are the sample sizes large enough for the Central Limit Theorem to apply?

Yes

or

No

mean = 0.260 standard error = 0.071 (b) Are... View the full answer

Part-a Mean of pa-pb is =0.42-0.16=0.26 Combined proportion... View the full answer
