Question

(a) A distribution of measurements is relatively mound-shaped with a mean of 60 and a standard deviation of 15. Use this information to find the proportion of measurements in the given interval. between 45 and 75 (b) A distribution of measurements is relatively mound-shaped with a mean of 40 and a standard deviation of 14. Use this information to find the proportion of measurements in the given interval. greater than 54 (C) A distribution of measurements has a mean of 65 and a standard deviation of 7. You know nothing else about the size or shape of the data. Use this information to find the proportion of measurements in the given interval. (Round your answer to two decimal places.) between 44 and 86
