LT 6E My Score Use the following scenario to answer the next four questions. At the stapler factory, red staplers are supposed to be 150 grams. The machine that makes the staplers has some variability, the distribution of the weights of the staplers is approximately normal with mean =150 grams and standard deviation o =22.5 grams. Suppose we choose an SRS of 30 staplers from this population and and calculate the mean weight i. 10. Calculate the mean and standard deviation of the sampling distribution of i . 11. Interpret the standard deviation from problem 10. I 12. Find the probability that the sample weight of the staples is under 135 grams
