Chapter 4: Q. 38 (page 285)

Use the following information to answer the next eight exercises: The Higher Education Research Institute at UCLA collected data from203,967incoming first-time, full-time freshmen from 270four-year colleges and universities in the U.S. 71.3%of those students replied that, yes, they believe that same-sex couples should have the right to legal marital status. Suppose that you randomly pick eight first-time, full-time freshmen from the survey. You are interested in the number that believes that same sex-couples should have the right to legal marital status.

X~鈥�(鈥�,鈥�)

Short Answer

Expert verified

The binomial distribution isX~B(8,0.713).

Step by step solution

01

Given information

Full time freshmen from 270four-year colleges.

Number of students replied is 71.3%.

Randomly selected full time freshmen in survey is8.

02

Explanation 

In binomial distribution Xvariables have,

Number of trials =8

Possibility of success=0.713

So,

X~B(T,P)

X~B(8,0.713)

Suppose you play a game with a spinner. You play each game by spinning the spinner once. P(red) = 25, P(blue) = 25, and P(green) = 15. If you land on red, you pay \(10. If you land on blue, you don't pay or win anything. If you land on green, you win \)10. Complete the following expected value table.

Define P(x),or the probability ofx.

Suppose that about 85% of graduating students attend their graduation. A group of 22 graduating students is randomly chosen.

a. In words, define the random variable X.

b. List the values that X may take on.

c. Give the distribution of X. X ~ _____(_____,_____)

d. How many are expected to attend their graduation?

e. Find the probability that 17 or 18 attend.

An instructor feels that 15% of students get below a C on their final exam. She decides to look at final exams (selected randomly and replaced in the pile after reading) until she finds one that shows a grade below a C. We want to know the probability that the instructor will have to examine at least ten exams until she finds one with a grade below a C. What is the probability question stated mathematically?

Suppose that you are performing the probability experiment of rolling one fair six-sided die. Let F be the event of rolling a four or a five. You are interested in how many times you need to roll the die in order to obtain the first four or five as the outcome. 鈥� p = probability of success (event F occurs) 鈥� q = probability of failure (event F does not occur)

a. Write the description of the random variable X.

b. What are the values that X can take on?

c. Find the values of p and q.

d. Find the probability that the first occurrence of event F (rolling a four or five) is on the second trial.
