The amount of money spent weekly on cleaning, maintenance, and repairs at restaurant was observed over a long period of time to be approximately normally distributed, with mean 1, = $780 and standard deviation of o = $53. How much should be budgeted for weekly repairs, cleaning, and maintenance so that probability that the budgeted amount will be exceeded in a given week is only 17%? (Round your answer to the nearest dollar.) Let X be the continuous random variable of the time students have to wait for Prof. Alvarez to arrive to class. The wait time, X, is uniformly distributed between -5 to 1 minutes to class. A negative means Prof. Alvarez arrived early to class and a positive means Prof. Alvarez arrived late to class. What is the probability that Prof. Alvarez arrives exactly on time? (Round your answer to two decimal places.) What is the probability that Prof. Alvarez arrives between -5 to 0 minutes early. (Round your answer to two decimal places.) What is the probability that Prof. Alvarez arrives between -5 to 1 minutes? (Round your answer to two decimal places.) Find the mean wait time for students. p = (Round your answer to two decimal places.) Find the standard deviation wait time for students. o = (Round your answer to two decimal places.)
