9. You are playing a card game, and the probability that you will win a game is p = 0.27. a. (3 pts) If you play the game 150 times, what is the most likely number of wins? (Round answer to one decimal place.) LL = b. (3 pts) Let X represent the number of games (out of 150) that you win. Find the standard deviation for the probability distribution of X. (Round answer to two decimal places.) O= c. (2 pts) The range rule of thumb specifies that the minimum usual value for a random variable is u-20 and the maximum usual value is u+20. You already found u and o for the random variable X. Use the range rule of thumb to find the usual range of X values. Enter answer as an interval using square-brackets and only whole numbers. usual values =T-Mobile Wi-Fi 12:22 AM @ 22% 0 a coursehero.com With df=252 and a=0.02, therefore to=2.341 C.I=3.4+2.341*1.6/V/253 =3.4+0.235 Upper confidence limit=3.4+0.235=3.635 Lower confidence limit=3.4- 0.235=3.165 The 98% confidence interval for the population mean number of visits per week is (3.165, 3.635) Therefore with 98% confidence the population mean number of visits per week is between 3.165 and 3.635 visits Is this answer helpful?
