What happens to the expected value of mA as the sample size increases? a. It decreases by x, b. T likewise increases. I. It remains stable. d The expected value does not change in a predictable manner as the sample size increases. ' 1. Samples of size n-9 are selected from a population with μ-fourscore with -is. What is meant by distribution of samples? a. lxxx b. 18 12. What proportion of the normal distribution lies in the tail beyond z1.00? C. 0.1587 D. -0.3413 A. -0.1587 b. 0.8413 xiii, a sample is obtained from a population with μ-100 and = 20, which of the following sample volition produce the most extreme z-score? a. A sample of n-100 scores with Thou = 102 b. A sample of n 100 scores with M-104 c. A sample of the N25 score with the M102D. A sample of n 25 scores with M-104 14. What proportion of the normal distribution lies in the tail beyond z 2.00? a. 0.0228 c. 0.4772 d. 0.0456 b. 0.9772 15. What happens to the standard error of M as the sample size increases? a. decreases. b. It remains stable. C. It likewise grows. When the sample size increases to -sixteen the standard error does non change in a predictable fashion. A normal distribution has a hateful of -20 with μ-100. If a score is chosen at random from this distribution, what is the probability that the value of the score will be between Ten – 80 and Ten – 1007 a. 0.1587 b. 0.3413 c. 0.8413 d. 0.6826 17. For a population with μ = fourscore and -|o, what is the 10 value respective to z = -0.l? a. .5 b. 85 d. 79.v eighteen. 40 and = 8, what is the z-score respective to X-46? Population a. +0.fifty b. +0.75 c. +i.00 d. +one.50 19. The mean of the distribution of the sample a. will be normal (or nearly normal) either if the population is normal or if the BCD sample size north 2 30 will only be normal (or nearly normal), then the sample size at least due north = xxx will always exist a normal (or nearly normal). The distribution volition be normal (or near normal) only if the population distribution is normal. xx. What proportion of the normal distribution lies between the hateful and z-0.forty? C. 0.1554 d. 0.6554 a. 0.3108 b. 0.3446

What happens to the expected value of mA as the sample size increases? a. It decreases by 10, b. T also increases. I. It remains stable. d The expected value does not change in a predictable way equally the sample size increases. ' 1. Samples of size due north-9 are selected from a population with μ-lxxx with -is. What is meant by distribution of samples? a. eighty b. 18 12. What proportion of the normal distribution lies in the tail beyond z1.00? C. 0.1587 D. -0.3413 A. -0.1587 b. 0.8413 13, a sample is obtained from a population with μ-100 and = 20, which of the post-obit sample will produce the most extreme z-score? a. A sample of north-100 scores with M = 102 b. A sample of northward 100 scores with M-104 c. A sample of the N25 score with the M102D. A sample of n 25 scores with Thou-104 14. What proportion of the normal distribution lies in the tail beyond z 2.00? a. 0.0228 c. 0.4772 d. 0.0456 b. 0.9772 15. What happens to the standard error of M equally the sample size increases? a. decreases. b. Information technology remains stable. C. It also grows. When the sample size increases to -sixteen the standard error does not change in a predictable mode. A normal distribution has a mean of -20 with μ-100. If a score is chosen at random from this distribution, what is the probability that the value of the score will exist between X – 80 and X – 1007 a. 0.1587 b. 0.3413 c. 0.8413 d. 0.6826 17. For a population with μ = lxxx and -|o, what is the Ten value corresponding to z = -0.50? a. .5 b. 85 d. 79.5 18. 40 and = eight, what is the z-score corresponding to X-46? Population a. +0.50 b. +0.75 c. +1.00 d. +1.fifty 19. The hateful of the distribution of the sample a. will exist normal (or nearly normal) either if the population is normal or if the BCD sample size north 2 thirty will be merely normal (or nearly normal), so the sample size at least n = 30 will always be a normal (or nearly normal). The distribution will be normal (or nigh normal) but if the population distribution is normal. 20. What proportion of the normal distribution lies betwixt the mean and z-0.40? C. 0.1554 d. 0.6554 a. 0.3108 b. 0.3446
