The average sunshine hours per year in a city have a normal distribution with a mean of 1,200 hours and a standard deviation of 118 hours. Use the normal distribution table given in the course notes to determine the probability that the sunshine hours per year are: • Less than 1,536.3 hours: P(z< 1,536.3) - • Between 1,208.26 and 1,358. 12 hours: P(1,208.26 < z < 1,358.12) – • More than 1,358. 12 hours: P(z > 1,358.12)- Keep 2 decimal Roints in the calculation of the standard normat variable (z), for using the standard normal distribution table in the course notes. Keep 4 decimal points in your answer according to the Standard Normal distribution table given in the course notes
