Extracted text: 1) A die is rolled 9 times and the number of times that two shows on the upper face is 1) counted. If this experiment is repeated many times, find the mean for the number of twos. 2) A final exam in Math 160 has a mean of 73 with standard deviation 7.8. If 24 students are randomly selected, find the probability that the sum of their test scores is less than 1824. Round your answer to 2 decimal places. 2) 3) Assume that the weight loss for the first month of a diet program varies between 5 pounds and 12 pounds, and is spread evenly over the range of possibilities, so that there is a uniform distribution. Sketch and label a uniform curve with the given information (rectangle). Then , find the probability that a person's weight loss is between 8 pounds and 11 pounds. Round your answer to 2 decimal places. 3)
