Given the new fad of health consciousness, a random sample of 400 college students was asked what their preferred type of drink was and whether they took regular or sugar free. The following table gives a two-way classification of the responses. Regular Sugar free TOTALS Juice 210 95 305 Iced Coffee 75 20 95 TOTALS 285 115 400 (a) If one student is selected at random from these 400 students, find the probability that this student (i) Prefers sugar free drinks (ii) Prefers juice (iii) Prefers regular juice (iv) Prefers juice given that it is a sugar free drink. (v) Prefers iced coffee or that drinks must be sugar free. (b) Are the events 'prefers juice' and 'prefers sugar free drinks' independent? Use probabilities to state your answer.

To test a new product, a fumigation company measured number of fleas capture in several homes, both before and after fumigation using this product. Assume that these homes can be considered a random sample of all homes the company has and will fumigate with this product. The before and after flea counts are given in this table: Home A B C D E F G Before 400 500 525 375 570 620 600 After 450 525 510 400 560 700 625 If we want to test whether the number of fleas is lower after using this product, which of the following is the correct standard error to use? 4.69 32.84 52.65 12.41 8.43
23. 3 Managers are processing incoming documents. First processes 40% of all documents, 2d processes 35% of all documents, 3d processes 25% of all documents. Probability of 1st manager making an error, while processing a document is 0.04, Probability of 2nd manager making an error, while processing a document is 0.06, Probability of 3rd manager making an error, while processing a document is 0.03. A document is picked up at random. It contains error. Find the probability: a. Document was processed by 1st manager b. Document was processed by 2nd manager c. Document was processed by 3rd manager

A CBS News poll involved a nationwide random sample of 651 adults, asked those adults about their party affiliation (Democrat, Republican or none) and their opinion of how the US economy was changing ("getting better," "getting worse" or "about the same"). The results are shown in the table below. better same worse Republican 38 104 44 Democrat 12 87 137 none 21 90 118 If we randomly select one of the adults who participated in this study, compute: (round to four decimal places)a.P(Republican) = b.P(same) = c.P(same|Republican) = d.P(Republican|same) = e.P(Republican and same) =
Is the following a null or an alternative hypothesis? Iced coffee tastes better than hot coffee.
There have been many studies that looked at the incidence of heart attack on the different days of the week. Studies in Japan and Scotland seemed to find that there was a substantial "spike" in heart attacks on Mondays, perhaps as much as 20% more. A researcher studied a random selection of 200 heart attack victims and recorded the day of the week that their attack occurred. The following table summarizes the results. Day Sunday Monday Tuesday Wednesday Thursday Friday Saturday Count 24 36 27 26 32 26 29 The researcher was interested in whether the distribution of heart attacks was the same or different across the days of the week. Under the appropriate null hypothesis, what is the expected number of heart attacks that occur on Monday? 36.0 28.6 Not within ± 1 of any of these 34.3 40.2
