Consider an urn with 3 red balls, 2 blue balls, and 1 white ball. You randomlydraw 2 balls sequentially from the urn without replacement. Every ball has the equalchance to be selected in each draw. Assume that order matters. Treat the balls identicalif they have the same color. "R" denotes the outcome of red ball. "B" denotes blue ball."W" denotes white ball.a. The sample space S for this experiment is {b. Consider the event A"none of the drawn balls is red". The list of all the samplepoints contained in the event A is {=c. Let X be the random variable counting the number of red balls in the experiment,then X is following adistribution.d. Let B be the event B = "at least 1 red ball is drawn". P(B) =result up to 2 decimal points.Save the final

In this problem, we will consider an urn containing red, blue, and white balls, and draw two balls…

Suppose that a sample space has five outcomes { 1, 2, 3, 4, 5}{O1,02,03,04,05} with corresponding weights w1 18w1%3D18, W23D14W2=D14, w33516Ww33516, and w4=116.W43D116. Answer the following questions:
Nationally, 83% of Americans have earned a high school diploma. We want to see if the proportion of Pennsylvania high school students who have a high school diploma is greater than 83%. Suppose a representative sample of 225 Pennsylvanians is taken and each is asked if they have earned a high school diploma. Consider the sample proportion p-hat of Pennsylvanians who have a high school diploma. If this was a true random selection of size 225 from a population of Pennsylvanians where 83% have earned a high school diploma, what would the mean and standard deviation of the sample proportion p-hat be?
Provide a reasonable description of the sample space for each of the random experiments. There can be more than one acceptable interpretation of each experiment. Describe any assumptions you make.
Two schools are investigating whether there is a difference in the proportion of students who attend the homecoming football game. Both schools have over 2,000 students. School A selected a simple random sample of 100 students and found that 98 attended the homecoming football game. School B selected a simple random sample of 150 students and found that 142 attended the homecoming football game. Let pˆc represent the combined sample proportion for the two schools, and let nA and nB represent the respective sample sizes. Have the conditions for statistical inference for testing a difference in population proportions been met? No, the condition for independence has not been met, because random samples were not selected from both schools. A No, the condition for independence has not been met, because the sample sizes are too large when compared to the corresponding population sizes. B No, the condition that the distribution of the difference in sample proportions…
A researcher is comparing the effectiveness of three devices designed to help people who snore. There are 210 people who snore participating in the experiment. Using a table of random digits starting from the first row and column, the researcher will randomly place the participants into three equally sized treatment groups suitable for comparison. Which number range would be needed to label the subjects correctly? O 0-2 O 1-3 O 000-210 O 001-210
1. Consider the following random experiment: there is a bag with 4 marbles in it, two red and two blue. We draw two marbles from the bag, without replacement. To make the sampling uniform, let's label the two red marbles R₁ and R2 and the two blue marbles B₁ and B2. Then the sample space is {R₁R2, R₁B₁, R₁B2, R2B1, R2B2, B1B2}. Finally, let X be the indicator variable equal to 1 if the two marbles drawn have the same color, and 0 if they have different colors. (a) Write down X as a function from the sample space to the real numbers. (b) What is Rx, the range of X? (c) Write down the probability mass function Px of X: this is a function from the range of X to the interval [0, 1]. (d) Identify the distribution of X by name, and give the parameter(s) of that distribution. (The functions in parts (a) and (c) of this problem both have only finitely many possible inputs. I don't care what notation you use in your answer, as long as you give me the value of the function for every possible…

A sports arena has three entrances (E1, E2, E3) and four different exits (X1, X2, X3, X4). As spectators come in, they enter through a random entrance E1,E2, or E3 and then exit through a random exit (X1,X2, X3, or X4). a. Create the sample space for this experiment listing all possible entrances and exits a spectator may use. Hint, how many outcomes are there? b. What is the probability a spectator enters from E3 and exits from X4? c. What is the probability a spectator does not enter from E1?
2. In a population it is estimated that 20% have a desired trait of interest for the researcher. The researcher wants to know how many people on average he has to draw from a population to get 2 people with the trait. Use rows 20-24 of the Random Number Table to carry out the simulation. Explain clearly how you set up the problem and report your findings. Answer:
