Starting at a particular time, each car entering an intersection is observed to see whether it turns left (L) or right (R) or goes straight ahead (S). The experiment terminates as soon as a car is observed to gostraight. Suppose that the random variable y denotes the number of cars observed.(a) What are possible y-values?O all positive whole numbersO all integersO all real numbers greater than 1all whole numbers greater than 1O all positive real numbers(b)List five different outcomes and their associated y-values.OutcomeValue of yRRSLLRLLS6.LRRS4RRRS4S.1.

Consider the following random experiment: we toss a two-sided coin (H on one side and T on the other side) n = 3616 times. In any given toss, the probability the coin comes up H is p = P(H) = 0.3. Each time the coin comes up H we give Tom 2 dollars and each time the coin comes up T we take from Tom 1 dollar (so Tom either gets 2 or gets -1, i.e., loses 1 dollar). How many dollars do we expect Tom will get on "average", i.e., per experiment?
Suppose there are three balls in a box. On one of the balls is the number 1, on another is the number 2, and on the third is the number 3. You select two balls at random and without replacement from the box and note the two numbers observed. The sample space S consists of the three equally likely outcomes {(1, 2), (1, 3), (2, 3)} (disregarding order). Let X be the sum of the two balls selected. Which of the following is the correct distribution for X?
These questions concerns the following situation. There is a rain on a football ground. The ground is 100 meters long and 70 meters wide. Model the event of a raindrop falling as a randomly selected point in the rectangle pictured.Lets imagine the following random variables: X is the x-coordinate where a raindrop falls, Y is the y-coordinate of where a raindrop falls, and Z=X+Y. CHOOSE ONE AND SHOW THE PROCESS. Which one of the following statements are true? * a) X and Y are independent b) X and Z are independent c) Y and Z are independent

A coffee shop claims that it takes 115 seconds, on average, to serve their customers coffeethrough the drive-thru. Lucy, a statistics student, decides to test this claim. She randomlyselects 15 orders and records the wait time it took for the customer to receive their coffee.Here are the times (in seconds). 85 122 135 100 153153 116 99 65 130175 113 188 142 134(a) Why is it important that Lucy selects a random sample of orders? (b) Lucy wants to make a confidence interval to estimate the true mean wait time. Explainthoroughly why Lucy has or has not satisfied the “normal” condition for constructing aconfidence interval. (c) The 95% confidence interval for the true mean wait time is (109.1, 145.6) seconds. Does theinterval provide convincing evidence that the coffee shop is lying about their claim? Explain.
An ordinary (fair) coin is tossed 3 times. Outcomes are thus triples of "heads" (h) and "tails" (*) which we write hth, ttt, etc. For each outcome, let N be the random variable counting the number of heads in each outcome. For example, if the outcome is ttt, then N (ttt) = 0. Suppose that the random variable X is defined in terms of N as follows: X=2N -2. The values of X are given in the table below. Outcome ttt hth tht htt thh hhh hht tth Value of X -2 2 0 0 2 4 2 0 Calculate the probabilities P(X=*) of the probability distribution of X. First, fill in the first row with the valuesof X. Then fill in the appropriate probabilities in the second row. Value x of X ___ ___ ___ ___ P(x=x) ___ ___ ___ ___
