A spinner with 8 equal sections is labeled 1 through 8. The spinner is spun 4 times. Three out of the 4 times, the arrow lands on 7. The predicted probability of the arrow landing on 7 is 1/8. Which statement BEST explains why the observed frequency is different from the predicted probability. * The spinner is spun more than 1 time.

The sample size is too small.
The section labeled 7 is bigger than the rest.
The predicted probability is incorrect.

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
