Which of the following probabilities for the sample points A, B, and C could be true if A, B, and C are the only sample points in an experiment? P(A) = 1/5, P(B) = 1/5, P(C) = 1/5 P(A) = 0, P(B) = 1/3, P(C) = 2/3 P(A) = 1/8, P(B) = 1/7, P(C) = 1/2 1/2, P(C) = 3/4 P(A)=1/4, P(B) =
Scenario: A researcher wants to know whether a hard copy of a textbook provides additional benefits over an e-book. She conducts a study where participants are randomly assigned to read a passage either on a piece of paper or on a computer screen. After a distractor task lasting 30 minutes, the participants are tested for their comprehension of the passage with a multiple-choice test containing 10 questions about their passage. Comprehension was scored using percent correct (0 — 100%). The researcher predicts that those randomly assigned to read the passage on a piece of paper will remember significantly more than those who read the passage online. Question: What is the scale of measurement of the dependent variable in this scenario? Nominal Ordinal Scale
2. If P (A) = 0.8, P(B) = 0.5, P(AUB) = 0.9, are events A and B independent events? Why or why not? Explain/show.
Event A and Event B are equally likely, mutually exclusive, collectively exhaustive and independent of each other. What is the value of P(A and B)?
Example 1 of the Chapter 9 Examples, we couldn't prove the player made over 80% of all of her free throws at the 1% significance level even though she made 53 out of 60 (which is 88.3%). (a) If she made 88.3% of the 60 free throws, why are we not able to show that she makes over 80%? (b) How many of the 60 would she have to make so that we could prove that she makes over 80% at the 1% significance level. Derive your answer mathematically (not by trial and error) (c) At what significance level would 53 out of 60 allowed us to prove she can make over 80%?
A survey shows that 75% of all respondents chose to have pizza for a mobie night. Suppose that another 8 friends participated in survey. Does it satisfy fixed number of trials? Does it have only 2 outcomes? Are all trials independent? Is it binomial experiment?
students were assigned a quiz that contains 7 independent multiple-choice problems. Each problem was worth 1 point and has 4 choices, where only one of them is correct. A pirate, who does not understand probability and statistics, disguises himself as a clever student and tried to pass one of the quizzes. Unlike our students, he is not able to solve the problems and, thus, decides to randomly choose an answer for each problem. Let X be a random variable representing the score of the pirate on the FIRST problem of the quiz. What distribution does X follow?
True or False: For a given experiment, it is possible to have two events A and B for which p(A) + p(B) > p(AUB). True False
Scenario 1: A surgeon routinely performs 4 surgeries. The chance that he performs surgery “A” is 30%. A random sample of 15 patients is selected. Let the variable X be defined as the number of patients that have surgery "A". Scenario 2: Thirteen (13) cards are randomly selected from a standard deck of cards without replacement. Let the variable X be defined as the number of spades selected. Directions: Pick a scenario describe a binomial experiment. Recall the random variable X is for the number of successes in a binomial experiment. • Be certain to state the criteria for a binomial distribution and how it does or does not meet each of the five conditions. Once your answer is posted, you will be able to see your classmates' responses.
Suppose we have a binomial experiment in which success is defined to be a particular quality or attribute that interests us. Use other parts of the question for help with answering the following question: What are the values of ?p̂ and ?p̂? (Use 3 decimal places.)

Question: What is the research / alternate hypothesis for this scenario? People who read a passage on a piece of paper will remember more than those who read a passage online. People who read a passage on a piece of paper will not remember more than those who read a passage online. Amount remembered of a passage will vary based…
