A repairman has 20 jobs that need to be completed today. Usually, 70% of all jobs are fairly straightforward, so that the time it takes to complete them is well-described by normal distribution with average 10 minutes and standard deviation 1 minute. The rest are challenging jobs, so that completion time is well-modeled with exponential distribution with average 1 hour.
i. If she starts at 8am, what is the expected time when she will finish all already assigned jobs?
ii. When asked when she will finish the jobs, she wants to give a safe answer by overestimating it by one standard deviation. Find the standard deviation for the time needed to finish all jobs.

Question #3.
A local consulting firm currently has
5 jobs that have to be completed by its contract employees. After
analyzing the time that it would take each specific employee to
complete each specific job, and, the wages each specific employee
is paid per hour, it determined how much it would cost if specific
employees were assigned to specific jobs. These costs were
calculated to be:
Cost ($)
