From the population of daily travel times, the average number of minutes traveled per day is said to be 38.8 minutes, (i.c. p. = 38.8)
From the population of daily travel times, the average number of minutes traveled per day is said to be 38.8 minutes, (i.c. p. = 38.8) with a corresponding standard deviation of 11.4 minutes (i.e.o =11.4). It is also known that the number of minutes traveled per day is normally distributed. Using the information given above, work out the empirical rule for this example, in the space provided below. BB 1 and 2: 63% BB 3 and 4: 95% BB 5 and 6: 99.7% For practice, put the information from above onto the curve, as we did in class. This will also help you answer the questions below. BB 7: Using ONLY the empirical rule, what is the probability a person will spend between 38.8 minutes and 61.6 minutes traveling in a day? *** BE AS PRECISE AS POSSIBLE*** BB 8: Using ONLY the empirical rule, what is the probability a person will spend between 16 minutes and 27.4 minutes traveling in a day? *** BE AS PRECISE AS POSSIBLE*** From all new employees hired at a large company in the last year, the average age is 31 years of age, with a corresponding standard deviation of 3.2 years of age. It is also known that age of all new employees is normally distributed. Using the information given above, work out the empirical rule for this example, in the space provided below. BB 9 and 10: 68% BB 11 and 12: 95% BB 13 and 14: 99.7% For practice, put the information from above onto the curve, as we did in class. This will also help you answer the questions below.

From all servings of Mac and Cheese boxes, the average number of noodles per box is said to be 476, with a corresponding standard deviation of 36. It is also known that the number of noodles in Mac and Cheese boxes is normally distributed.
