Suppose that you randomly draw one card from a standard deck of 52 cards. After writing down which card was drawn, you replace the card, and draw another card. Yourepeat this process until you have drawn 16 cards in all. What is the probability of drawing at least 7 clubs?For the experiment above, let X denote the number of clubs that are drawn. For this random variable, find its expected value and standard deviation.E(X) =σ =

At a local bar in North Park, 57% of bargoers order their specialized homemade beer. They advertise their homemade beer and want to know if the proportion has increased. From 140 randomly selected customers, 67% of the 140 ordered the specialized homemade beer. Our test is given as, Ho: p = 0.57 Ha: p > 0.57 with a p-value of 0.0084. The manager at the bar concludes the probability that the population proportion is greater than 0.57 is 0.0084. Is he correct or incorrect in his interpretation? Explain your reasoning.
A believer in the "random walk" theory of stock markets thinks the value of an index of stock prices has a 0.6 probability of rising in any year. The change in the value of the index in any given year is not affected by whether it rose or fell in earlier years. You plan to record the value for the index in each of the next eight years. Let the random variable, X, represent the number of years (out of the next 8 years) in which the value of the index rises. a) If X is distributed according to the binomial probability distribution, what are the values for n and p?o b) What are the possible values X can take, or equal? QMETH 201, Homework 3 c) Calculate the probability X = 30 d) Calculate the expected value for X. e) Calculate the standard deviation for X. 4
