Exercise 5. New School Structure The Dean of a college wants to use the proportion of a population to determine the sample size needed to interview regarding their thoughts about the new school structure. She wants to be able to assert with a probability 0.95 that her error will be at most 0.05. Similar polls in the past showed that 65% approved the new structure. How large a sample does the Dean need? Solution: (a) Known Information: Za/2 –E =,

The amount of time, T, that the effect of caffeine is felt on your body after drinking a cup of coffee is given by a continuous random variable with an exponential distribution. On average, caffeine is felt for about 5 hours after drinking the cup. (Answer part a-c) a. What is the probability that the effect lasts at least 4 hours? b. What is the probability that the effect lasts fewer than 6 hours? c. You usually go to sleep at 11:30 pm, and drink exactly one cup of coffee a day. Suppose you wish to guarantee at most a 5% chance of feeling the effects of caffeine when you go to sleep. What's the latest that you should drink your only cup of coffee?
