A study was conducted to determine whether there were significant differences between college students admitted through special programs (such as retention incentive and guaranteed placement programs) and college students admitted through the regular admissions criteria. It was found that the graduation rate was 91.5% for the college students admitted through special programs. If 11 of the students from the special programs are randomly selected, find the probability that at least 10 of them graduated. prob If 11 of the students from the special programs are randomly selected, find the probability that eactly 8 of them graduated. prob Would it be unusual to randomly select 11 students from the special programs and get exactly 8 that graduate? no, it is not unusual yes, it is unusual If 11 of the students from the special programs are randomly selected, find the probability that at most 8 of them graduated. prob = Would it be unusual to randomly select 11 students from the special…

A local country club has a membership of 600 and operates facilities that include an 18-hole championship golf course and 12 tennis courts. Before deciding whether to accept new members, the club president would like to know how many members regularly use each facility. A survey of the membership indicates that 69% regularly use the golf course, 45% regularly use the tennis courts, and 10% use neither of these facilities regularly. Given that a randomly selected member uses the tennis courts regularly, find the probability that they also use the golf course regularly.

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.
A survey on the best Asian tourist destinations showed that, out of 70 people, 23 ranked Singapore as first, whereas 15 put Hong Kong in first place, 11 put Shanghai first, 7 put Beijing first, and the rest of them chose Tokyo. On the basis of this data, calculate the following.a. The probability of the preferred destination being a city in China. (In this specific case, Hong Kong is not considered part of China.)b. The probability of the preferred destination not being a Chinese city. (In this case, Hong Kong is considered a Chinese city, even if outside China.)c. The probability of the preferred destination being Tokyo.d. The probability of the preferred destination not being Singapore.
A survey showed that 80% of adults need correction (eyeglasses, contacts, surgery, etc) for their eyesight. If 19 adults are randomly selected find the probability that no more than 1 of them need correction for their eyesight. Is 1 significantly low number of adults requiring eyesight correction. a. The probability that no more than 1 of the 19 adults require eyesight correction is b. Is 1 significantly low number of adults requiring eyesight correction: Note that a small probability is one that is less than 0.05.
1. Researchers are interested in the relationship between vaping and upper respiratory infections. Suppose that 15% of their population of interest has vaped in the past year and 25% have had an upper respiratory infection in the past year. In addition, they know that 10% have both vaped and had an upper respiratory infection in the past year. What percent of the population has neither vaped nor had an upper respiratory infection in the past year? b. What is the probability of having an upper respiratory infection in the past year given that the person has vaped in the past year? What is the complement of the event in part b)? Be sure to interpret this probability in the context of the problem. a. C. d. What is the probability of having an upper respiratory infection in the past year given that the person has not vaped in the past year? Are the two events independent? Be sure to justify your answer. Based on your calculations what can you conclude about the relationship between vaping…
