Suppose 1495 Valencia College students were selected at random from the entire student body and given an experimental H1N1 flu shot. All 1495 were exposed to the flu, but only 332 of them actually ended up sick with the flu. Let p represent the probability that the flu shot will be successful. (Read this carefully!) A. Find the point estimate for the population proportion from this study. Show your simplified fraction for the point estimate. Use proper notation. B. Build a 98% confidence interval for the real population proportion by hand using the formula. Draw a picture that represents the problem and clearly indicate your final answer CUse a complete sentence or two to interpret your confidence interval

Suppose you are interested in knowing the proportion of Texas A&M students who have their own subscription to Netflix.  Everyone in a class of 77 students takes a random sample of 100 Texas A&M students and asks them if they have their own Netflix subscription. Each person calculates the proportion of their sample with a subscription and we make a histogram of the 77 proportions.  What kind of distribution would be displayed in that histogram?    a. Population Distribution   b. Sampling Distribution   c. Data Distribution   d. Parent Distribution   e. More than one of the above

Suppose that 9% of all athletes in a sport use a banned drug. A test is available that detects 94% of athletes who use the drug. But the test also gives a positive result for 8% of those who do not use the drug. What percent of athletes who test positive for the drug are actually using the drug? Answer: 77.28 %
