Please help me solve this as many as you can. Thank you. 1/ Doing research for insurance rates, it is found that those aged 30 to 49 drive an average of 38.7 miles per day with a standard deviation of 6.7 miles. These distances are normally distributed. If a group of 60 drivers in that age group are randomly selected, what is the probability that the mean distance traveled each day is between 29.9 miles and 39.9 miles? 2/ A...

Jeff's bowling scores are approximately normally distributed with mean 130 and standard deviation 15, while Jill's scores are normally distributed with mean 125 and standard deviation 24. If Jeff and Jill each bowl one game, then assuming that their scores are independent random variables, approximate the probability that the total of their scores is above 260.
