1. The five-number summary for midterm scores (number of points; the maximum possible score was 50 points) from an intro stats class is: MinQ1MedianQ3Max16.5323943.548.5 a. Would you expect the mean midterm score of all students who took the midterm to be higher or lower than the median? Explain. b. Based on the five-number summary, are any of the midterm scores outliers? Explain.

Suppose 0<P(A)>1 and 0<P(B)<1. If A implies not B then (select all that apply) A: A and B are mutually exclusive B: A and B are independent C: A and B are dependent D: A is a subset of B E: B is a subset of A F: not A is a subset of B G: not B is a subset of A H: A is a subset of not B I: B is a subset of not A J: not B is a subset of not A K: not A is a subset of not B L: none of […]

The label on the bag of a certain brand of potato chips claims the bag contains 52 grams of chips. In fact, weights of chips per bag are known to follow a normal distribution with standard deviation 1.7 grams. What must be the mean weight of all bags of chips in order for only 12% of bags to have weights below the amount on the label 

Which of the following data sets approximates a Normal Distribution? Which is a Positive Skew? Which is a Negative Skew? Which data set has the highest Mean, Median and Mode? A. 2, 4, 4, 5, 5, 5, 5, 6, 6, 8. B. 2, 4, 4, 4, 5, 5, 5, 6, 7, 10. C. 1, 2, 3, 4, 5, 7, 7, 7, 8, 8. D. 1, 2, 4, 5, 5, 8, 8, 8, 9, 9. How did you determine your answer?
