The manager of a restaurant believes that waiters and waitresses who introduce themselves by telling customers their names will get larger tips than those who don't. In fact, she claims that the average tip for the former group is 16% while that of the latter is only 12%. If tips are normally distributed with a standard deviation of 8%, what is the probability that in a random sample of 15 tips recorded from waiters and waitresses who introduce themselves and 15 tips from waiters and waitresses who don't, the mean of the former will exceed that of the latter? Probability= 16.75

One year, demand for sperm whale oil was particularly high and Captain Ahab decided to hunt onlythose whales. The length of a sperm whale in the 1840s was normally distributed with mean 16.1meters and standard deviation 1.5 meters.(a) What is the probability that the first four whales they catch are all longer than 16.4meters?(b) If the selection and capture of the whales is random, what is the probability that themean length of the first 25 whales they capture is at least 16.3 meters.(c) Upon return to Nantucket, Captain Ahab reports how many whales they caught, andthat the mean length of sperm whales they caught was 16.3 meters. His colleague Captain Bildadexclaims, “But there’s less than a 1% chance of getting a mean that high or higher if the truepopulation mean and standard deviation are what we think they are!”Approximately how many whales did Ahab tell Bildad they caught?(d) The next year, they catch 123 whales with a mean length of 16.4 meters, and astandard deviation of 1.4…

A management consultant found that the amount of time per day spent by executives performing tasks that could be done equally well by subordinates followed a normal distribution with a mean of 2.4 hours. It was also found that 10% of executives spent over 3.5 hours per day on tasks of this type. For a random sample of 400 executives, find the probability that more than 80 spend more than 3 hours per day on tasks of this type.
