Suppose you are looking at the bus routes for chapel hill. it is important that buses arrive on time, and not run late or come too early. you investigate one of the routes and take a 'sample' of 15 circuits, monitoring the time it takes for a bus to complete one full cycle of its route. the mean time to complete the route based on this information was 55 minutes, with a sample standard deviation of 10 minutes. the bus is supposed to take 60 minutes to complete its route. you want to know whether the bus route is completing its route on time with 95% confidence. (assume normally distributed times) construct a null and alternative hypothesis that represents this situation.

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.
