450 people are randomly selected at grocery stores across the state and surveyed on the amount of money they are spending at the store that day. how does finding the sample variance compare to investigating the sampling distribution of the variance? a. since the state has at least 450 grocery stores, finding the variance of the sample is the same as investigating the sampling distribution of the variance. b. the sampling distribution of the variance requires repeating this process with the same sample several times. so this does not compare to the sampling distribution of the variance. c. only 450 people are selected from all the shoppers, so the distribution is not even. d. the sampling distribution of the mean requires multiple samples to be compared. however, in this situation you are looking for the variance, so finding the sample variance is the same as investigating the sampling distribution of the variance.

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
