A box contains three marbles: one red, one green and one blue. Consider an experiment that consistsof taking one marble from the box then replacing it in the box and drawing a second marble fromthe box. One possible outcome is (R,B) (the first pick is red and the second pick is blue).(a) List all outcomes in the sample space .(b) If, at all times, each marble in the box is equally likely to be selected, what is the probabilityof each sample point in the sample space?(c) What is the probability that the first pick is green and the second pick is not green?

From the given information we have a box containing three marbles: one red, one green, and one blue.…

3. Bayesian Inference A cab was involved at night in a hit and run accident. In this town there are only two cab companies, the Blue with 80% of the cabs and the Green company with the remaining 20%. As it happened there was a witness to the accident who identified the hit and run cab as Blue. The case came to trial. An important part of the testimony was a test of the reliability of the eyewitness to identify a cab as being either Blue or Green under the same circumstances as those that existed the night of the accident. The result of these tests was that the witness correctly identified a blue cab as blue 70% of the time and a green cab as green 80% of the time. On the basis of the claim of the eyewitness and the test conducted by the court, what is the probability that the cab involved in the accident was in fact Blue as the witness had claimed?
An experiment compares the taste of instant coffee versus fresh brewed. Each subject tastes two unmarked cups of coffee – in random order – and states which he or she prefers. Of the 50 who participate, 19 (or 38%) prefer the instant coffee while the remaining 31 (or 62%) prefer the fresh brewed. Let pdenote the proportion of the population who prefer fresh-brewed over instant. We wish to test if people prefer fresh-brewed over instant. Which of the following are the appropriate null and alternative hypotheses? Hint: if people cannot tell the difference between fresh brewed and instant, what would that make the value of p be? The null hypothesis is H0: ["", "", "", ""] The alternative hypothesis is Ha:
Ecologists conducted a study to investigate the potential ecological impact of golf courses. Investigators monitored the reproductive success of bluebirds in birdhouses at nine golf courses and ten similar birdhouses at nongolf sites. Data on nests in birdhouses occupied only by bluebirds are shown in the table. If the proportions of nests occupied is the same for golf and nongolf sites, what would be the expected count of birdhouse with 1 nest in nongolf locations?

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
The management of a company finds that 30% of the administrative assistants hired are unsatisfactory. The personnel director is instructed to devise a test that will improve the situation. One hundred employed administrative assistants are chosen at random and are given the newly constructed test. Out of these, 95% of the satisfactory administrative assistants pass the test and 15% of the unsatisfactory administrative assistants pass. Based on these results, if a person applies for a job, takes the test, and passes it, what is the probability that he or she is a satisfactory administrative assistant? If the applicant fails the test, what is the probability that he or she is a satisfactory administrative assistant? Draw the tree diagram. Choose the correct answer below.

A friend of mine is giving a dinner party. His current wine supply includes 7 bottles of zinfandel, 11 of merlot, and 13 of cabernet (he only drinks red wine), all from different wineries. (a) If he wants to serve 3 bottles of zinfandel and serving order is important, how many ways are there to do this? (b) If 6 bottles of wine are to be randomly selected from the 31 for serving, how many ways are there to do this? (c) If 6 bottles are randomly selected, how many ways are there to obtain two bottles of each variety? (d) If 6 bottles are randomly selected, what is the probability that this results in two bottles of each variety being chosen? (Round your answer to three decimal places.) (e) If 6 bottles are randomly selected, what is the probability that all of them are the same variety? (Round your answer to three decimal places.)
A basketball player makes 75% of his shots during games. We can use a chance device to simulate whether or not this player will make a shot. Which TWO situations below would NOT be a good simulation model? (Choose two answers!) RandInt(1, 100): Let numbers 1-75 represent a make and numbers 76-100 represent a miss. Random number table: Pick two digits at a time. Let 01-75 represent a make and 76- 100 represent a miss. Random number table: Pick two digits at a time. Let 01-75 represent a make and 76- 99 and 00 represent a miss. Pick a card from a deck: Let a heart, diamond, or spade represent a make. Let a club represent a miss. Roll a die: let numbers 1,2,3, 4 represent a make and let 5 and 6 represent a miss.
A study compares students who use a website and students who do not use the website. In addition to asking the students in the samples about GPA, each student was also asked how many hours he or she spent studying each day. The two samples (141 students who were users of the website and 68 students who were not users of the website) were independently selected from students at a large, public university. Although the samples were not selected at random, they were selected to be representative of the two populations. n USE SALT For the sample of users of the website, the mean number of hours studied per day was 1.46 hours and the standard deviation was 0.83 hours. For the sample of students who do not use the website, the mean was 2.77 hours and the standard deviation was 0.99 hours. Do these sample data provide convincing evidence that the mean time spent studying for users of the website at this university is less than the mean time spent studying by students at the university who do…
In a survey, it was found that 80% of adults operate the flusher of toilets in public restrooms with their foot. (a) If 300 adults are randomly selected, how many would we expect to flush toilets in public restrooms with their foot? (b) Would it be unusual to observe 255 adults who flush toilets in public restrooms with their foot? (a) We would expect (Type a whole number.) adults to flush toilets in public restrooms with their foot. (b) Would it be unusual to observe 255 adults who flush toilets in public restrooms with their foot? Choose the correct answer below. O A. Yes, because 255 is greater than u + 2o. O B. No, because 255 is greater than u + 20. O C. Yes, because 255 is between u - 20 and u+ 20. O D. No, because 255 is less than u- 20. O E. No, because 255 is between u -20 and u+ 20.
