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...

Harry consumes caffeinated beverages at an average rate of 3 per day. (a) Find the probability that the time between two caffeinated beverages is greater than 9 hours. Derive the formulation using the cumulative distribution function, but do not calculate it. (b) Find the probability that the time until Harry consumes 10 caffeinated beverages is less than 4 days. (c) Calculate the expected time until Harry consumes 10 caffeinated beverages.

Please write neatly ?
Problem 4 Four-year-olds in China average 5 unsupervised hours per day. Most of the unsupervised children live in rural areas, considered safe. Suppose that the amount of unsupervised time is normally distributed with standard deviation 1 A Chinese 4-year-old is randomly selected from a rural area. We are interested in the amount of time the child spends alone per day. In each appropriate box you are to enter either a rational number in "p/q" format or...
