Choose all that are correct. a) Random samples from the same population will vary from sample to sample.
b) As the sample size increases, the sample distribution more closely resembles the population distribution.
c) Values of a sample statistic of different random samples of the same size from the same population will be the same.
d) If a random sample is chosen from a population with a large cluster of points at the maximum, the sample is likely to have at least one element near the maximum.

If your score on your next statistics test is converted to a z score, which of these z scores would you prefer: minus2.00, minus1.00, 0, 1.00, 2.00? why? a. the z score of 2.00 is most preferable because it is 2.00 standard deviations above the mean and would correspond to the highest of the five different possible test scores. b. the z score of 0 is most preferable because it corresponds to a test score equal to the mean. c. the z score of minus2.00 is most preferable because it is 2.00 standard deviations below the mean and would correspond to the highest of the five different possible test scores. d. the z score of minus1.00 is most preferable because it is 1.00 standard deviation below the mean and would correspond to an above average
