2.3-15. Apples are packaged automatically in 3-pound bags. Suppose that 4% of the time the bag of apples weighs less than 3 pounds. If you select bags randomly and weigh them in order to discover one underweight bag of apples, find the probability that the number of bags that must be selected is (a) At least 20. (b) At most 20. (c) Exactly 20.

You may want to create a table to help you with this problem. Consider a computer test to indicate if you like Math 123 or dislike Math 123. If positive, you like the class and if negative you dislike the class. In a sample of 25 thousand people, 80% of the population indicated they liked the class. If the test is 85.5% accurate, what are the chances that the test showed the person disliked Math 123, but in reality they actually liked the course? Round your percentage to 2 decimals.

Please solve this question below. Thank you! 9. Challenge A bag contains 200 red and blue marbles. Three people each took samples of 25 marbles and noted the number of red marbles. Person A 17 red marbles out of 25 marbles Person B 12 red marbles out of 25 marbles Person C 20 red marbles out of 25 marbles a. Combine the samples to make one large sample. Use that sample to predict the number of red marbles in a similar bag that contains 300 marbles. b. Explain how having a fourth sample would make the estimate better.
