Tonya wants to estimate what proportion of her school's seniors plan to attend the prom. She interviews an SRS of 50 of the 750 seniors in her school and finds that 36 plan to go to the prom. Construct a 90% confidence interval for p. Show your method.

Select the best answer. In a congressional district, 55% of the registered voters are Democrats. Which of the following is equivalent to the probability of getting less than 50% Democrats in a random sample of size 100? (a)

$$P \left( Z < \frac { 0.50 - 0.55 } { 100 } \right)$$

(b)

$$P ( Z < \frac { 0.50 - 0.55 } { \sqrt { \frac { 0.55 ( 0.45 ) } { 100 } } ) }$$

(c)

$$P ( Z < \frac { 0.55 - 0.50 } { \sqrt { \frac { 0.55 ( 0.45 ) } { 100 } } ) }$$

(d)

$$P \left( Z < \frac { 0.50 - 0.55 } { \sqrt { 100 ( 0.55 ) ( 0.45 ) } } \right)$$

(e)

$$P \left( Z < \frac { 0.55 - 0.50 } { \sqrt { 100 ( 0.55 ) ( 0.45 ) } } \right)$$

Choose the best answer. A set of 10 cards consists of 5 red cards and 5 black cards. The cards are shuffled thoroughly, and you choose one at random, observe its color, and replace it in the set. The cards are thoroughly reshuffled, and you again choose a card at random, observe its color, and replace it in the set. This is done a total of four times. Let X be the number of red cards observed in these four trials. The random variable X has which of the following probability distributions? (a) The Normal distribution with mean 2 and standard deviation 1 (b) The binomial distribution with n = 10 and p = 0.5 (c) The binomial distribution with n = 5 and p = 0.5 (d) The binomial distribution with n = 4 and p = 0.5 (e) The geometric distribution with p = 0.5

(a) A light-rail commuter train accelerates at a rate of 1.35 m/s². How long does it take to reach its top speed of 80.0 km/h, starting from rest? (b) The same train ordinarily decelerates at a rate of 1.65 m/s². How long does it take to come to a stop from its top speed? (c) In emergencies, the train can decelerate more rapidly, coming to rest from 80.0 km/h in 8.30 s. What is its emergency acceleration in meters per second squared?
