One professional basketball player typically attempts eight free throws per game. Let X represent the number of free throws made out of eight. The distribution for X is shown in the table. Which of the following is the correct interpretation of P(X ≤ 3)? The probability of the number of free throws made out of 8 is at most 3. The probability of the number of free throws made out of 8 is at least 3. The probability of the number of free throws made out of 8 is lower than 3. The probability of the number of free throws made out of 8 is higher than 3.
Flip two fair coins. Then the sample space is {HH, HT, TH, TT} where T = tails and H = heads. The outcomes HT and TH are different and the HT means that the first coin showed heads and the second coin showed tails.

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.
