Question

Select one answer Every simulation in this module is based on an assumption about the difference between two population proportions. The population proportions affect the mean and the standard error of the differences in sample proportions. The sample size also affects the standard error. io points The distribution of differences between sample proportions shown below has mean o.35, and a standard error of about o.10 Frequencies of p-P2 Values Which of the following did we use to generate this sampling distribution? A. O Population proportions of o.85 and o.65 with samples of size 35. B. OPopulation proportions of o.85 and o.50 with samples of size 35. C. Population proportions of o.85 and 0.50 with samples of size 20. D. O Population proportions of o.85 and o.65 with sample sizes of 20

Explanation / Answer

Q-1.

Mean of distribution of p1 - p2 = 0.35 So, Correct option : b or c,

The area of any portion of the histogram (the area under any part of the curve) is the proportion of the population in the designated region. It is also the probability that an individual selected at random will have a value in the designated region.
