- In each of the examples that follow, determine what value the random variable would assign to the specific outcome listed. You have some number of coins in your pocket, and you choose two at random. The random variable ZZ assigns the value of the coins in cents to each outcome. What value is assigned when you draw out a quarter and a dime? A coin is flipped three times. YY is a random variable that assigns 3 times the number of heads flipped minus 2 times the number of tails flipped. What number is assigned to HHT? A person picks a number between 1 and 272820. The random variable ZZ assigns the 0 to an even number and 1 to an odd number. What number is assigned to 270221?Fill in the blank. The states that if, under a given assumption, the probability of a particular observed event is exceptionally small (such as less than 0.05), we conclude that the assumption is probably not correct. The probably not correct states that if, under a given assumption, the probability of a particular observed event is exceptionally small (such as less than 0.05), we conclude that the assumption isBased on a survey, assume that 28% of consumers are comfortable having drones deliver their purchases. Suppose that we want to find the probability that when five consumers are randomly selected, exactly three of them are comfortable with delivery by drones. Identify the values of n, x, p, and q. The value of x is 3. (Type an integer or a decimal. Do not round.) The value of p is 0.28 . (Type an integer or a decimal. Do not round.) Question The value of q is (Type an integer or a decimal.
