QUESTION 11A gambler belives that he has learned to predict the color of a card befroe it is drawn from the deck. In order to test this,he predicts a color, draws a card from a fresh deck of 52 cards and observes its color, replaces the card, and then shuffles.He repeats this process 19 times, and finds that he got 15 predictions incorrect.Using a sign test, test the hypothesis that the gambler is getting fewer predictions inccorect than one would expect due tochance.sig = ?QUESTION 12Click Save and Submit to save and submit.

A random sample of 88 U.S. 11th-12th graders was selected. The two-way table summarizes the gender of the students and their response to the question “Do you have allergies?” Suppose we choose a student from this group at random. If the student has allergies, what is the probability that the student is female?
Sheila is conducting an experiment in which she is rolling a die. After rolling the die 90 times, she has collected the following data. Based on theoretical probability, she was expecting the die to land on each number 15 times. Sheila then remembered that experimental probability does not always equal theoretical probability, but it should approach it the more times an experiment is run. Sheila ran the experiment again rolling the die 180 times. For the 180 rolls of the die, she noticed that all of the frequencies were at most 20% away from what was expected based on the theoretical probability. She then combined the two data sets for a total of 270 rolls of the die. The minimum frequency that she could have obtained from any number in the combined data set is :______________ and the maximum frequency she could have obtained from any number is: _______________
Wendy needs to get to an airport from a hotel. There is 0.33 chance that she calls a cab, there is 0.11 chance that she gets a Uber. If she cannot get a cab or Uber, she will take a shuttle. If she calls a cab, there is 0.29 chance that she could miss the flight. If she gets a Uber, the chance of missing flight is 0.22. If she takes the shuttle, the chance is 0.28. What is the probability that she misses the flight? (Round your answer to three decimal places)
An anger-management course claims that, after completing its seminar, participants will lose their tempers less often. Always a skeptic, you decide to test this claim. A random sample of 12 seminar participants is chosen, and these participants are asked to record the number of times that they lost their tempers in the two weeks prior to the course. After the course is over, the same participants are asked to record the number of times that they lost their tempers in the next two weeks. The following table lists the results of the survey. Using these data, test the claim at the 0.01 level of significance assuming that the population distribution of the paired differences is approximately normal. Let participants before completing the anger-management course be Population 1 and let participants after completing the anger-management course be Population 2.

1. In the casino game Roulette, a bet on “red” will win if the ball lands on one of the 18 red numbers of the 38 numbers on the wheel, with each number being equally likely. You want to run a simulation that will estimate the probability of a player winning both bets when betting on red twice. Which of the following would be an appropriate setup for the simulation: I. Use a table of random digits to select one number from 01 to 38 and then a second number from 01 to 38. If the first number is between 01 and 18 and the second number is between 01 and 18, then the player has won both rounds. II. Use a table of random digits to select two numbers 01-38, without repeats. If both numbers are between 01 and 18, then the player has won both rounds. III. Use a table of random digits to select two numbers 01-19, allowing repeats. If both numbers are between 01 and 09, then the player has won both rounds. (A) I (B) II (C) III (D) I and II (E) I and III

QUESTION 11 A critical thinking professor asked her students to indicate whether they believed each of two headlines. One headline was false, and the other was true, but the students did not know this. The probability that a student selected at random believed the true headline was 89% and the probability that the student believed the false headline was 85%. She found that 7896 of the students believed both headlines. a. In this sample, are the events "believed the false headline" and "believed the true headline" mutually exclusive? Explain b. Find the probability that a randomly selected student from this sample believed the true headline OR believed the false headline.

A study reported that about 40% of high school students have tried out for a sport at their school. To find out if this applies to Jessica’s school, she surveyed an SRS of 20 students. Nine of them said that they had tried out for a sport. To see if this result is surprising, a simulation is to be conducted to estimate the probability of obtaining a sample result as high as this one. Let 0–3 represent students who tried out for a sport and 4–9 represent students who did not try out for a sport. Using the line of random numbers to run one simulation, what proportion of students tried out for a sport? 0.40 0.45 0.50 0.60
On Mr. Casper's debate team at Thunderbird High School, 20% of the members are Sophomores, 35% are Juniors and 45% are Seniors. A team member is selected randomly to give the closing argument for the team. If a sophomore gives the closing argument, the team has a probability of 0.25 of winning the debate. If a junior gives the closing argument, the probability of winning is 0.6. If a senior closes, the probability of winning is 0.85. (a) Find the probability that the team wins the debate. b sketch a tree diagram to model this process
Itranscript One male and one female dam rat pup were randomly selected from 8 litters to perform the swim maze. Each pup was placed in the water at one end of the maze and allowed to swim until it escaped at the opposite end. If the pup failed to escape after a certain period of time, it was placed at the beginning of the maze and given another chance. The experiment was repeated until each pup accomplished three successful escapes. The table to the right reports the number of swims required by each pup. Is there sufficient evidence of a difference between the mean number of swims required by male and female pups? Use a=0.01. Comment on the assumptions required for the test to be valid.

(b) Let E be the event that the first car turns right. List the outcomes of E. (c) Compute P(E). (d) Let F be the event that at least one of the cars turns left. List the outcomes of F. (e) Compute P(F).
