Asoft-drink machine at a steakhouse is regulated so that the amount of drink dispensed is normally distributed with a mean of 200 milliliters and a standard deviation of 15 milliliters. the soft-drink machine is checked by taking a sample of 9 drinks and computing the average amount of drink dispensed, which is 203 milliliters. the steakhouse manager is concerned that the amount of soft-drink dispensed is more than 200 milliliters. use the 5% significance level. what is the alternative hypothesis associated with the steakhouse manager’s concern?

Air at a pressure of 1atm and a temperature of 40 c is in parallel flow over the top surface of a flat plate that is heated to a uniform temperature of 120 c. the plate has a length of 0.40m (in the flow direction) and a width of 0.15m. the reynolds number based on the plate length is 50, 000. what is the rate of heat transfer from the plate to the air? if the free stream velocity of the air is doubled and the pressure is increased to 10 atm what is the rate of heat transfer?
