Suppose we are again given 20 tulip bulbs that are very similar in appearance. Information on this new set of tulips is summarized below: Early (E) Late (L) Totals Red (R) Yellow (Y) Totals 5 5 10 5 5 10 10 10 20 What is P(Y)? (Enter the probability with two decimal places)

Select 3 courses from a list of 7. How many different courses can be selected? Group of answer choices 7*6*5 = 210 (7*6*5)/3 = 70 (7*6*5)/(3*2*1)  = 35 3*7 = 21 7*6 = 42

Using the random variables X and Y from Table 2.2, consider two new random variables W = 4 + 8X and V = 11 - 2Y. Compute (a) E(W) and E(V); (b) J2W and J2V; and (c) JWV and corr(W, V).

26. Expedia would like to test that the average number of Southwest Airlines flights which arrive on time (u) is 90. A random sample of 140 flights found that 119 arrived on time. Suppose a = 0.05. Then the critical value for the test %3D (Za/2) is a) 1.28 b) 1.96 c) 2.33 d) 2.58 O b O a Oc

You may need to use the appropriate technology to answer this question. Emergency 911 calls to a small municipality in Idaho come in at the rate of one every four minutes. Assume that the number of 911 calls is a random variable that can be described by the Poisson distribution. (a) What is the expected number of 911 calls in 1 hour? 15 (b) What is the probability of three 911 calls in 5 minutes? (Round your answer to four decimal places.) x (c) What is the probability of no 911 calls in a 5-minute period? (Round your answer to four decimal places.) x
