Round to the fourth as needed for all parts. Use your calc unless for all parts except parts A and B.
Suppose in February 2014, a local police department in Minnesota reported that 59.7% of petty crimes go
unsolved. Assume these petty crimes follow a binomial distribution. A sample of 14 petty crimes is taken.
A. Input the number of combinations that are possible for exactly 4 petty crimes that go unsolved.
After canceling all the denominators in the previous part, what numbers did you have in the numerator
before multiplying to get your answer

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
