To investigates a problem an independent watchdog agency contacts a random sample of 20 airport and collected information on the number of complains the airport had with etickets for the month of March. At the 0.05 significance level, can the watchdog agency concludes the mean number of complains per airport is less than 15 per month. conduct a test of hypothesis and interprets the results.

One of the most important contributors to work-life balance identified by the survey was "flexibility," with 41% of women saying that having a flexible work schedule is either very important or extremely important to their career success. Suppose you select a sample of 100 working women. d.) If a sample of 400 is taken how does this change your answer to b? The probability that in the sample between 37% and 47%say that having a flexible work schedule is either very important or extremely important to their career success is____.

Of those stolen byprofessionals, 24% were recovered within 48 hr, 16% were recovered after 48 hr and 60% were never recovered.Of those vehicles presumed stolen by amateurs, 38% were recovered within 48 hr, 58% were recovered after 48 hrand 4% were never recovered. a) Draw a tree diagram representing the situation.b) What is the probability that a vehicle stolen by a professional in this city and will be recovered within 48 hr?c) What is the probability that a vehicle stolen in this city will never be recovered?
- 10. In 1974, Loftus and Palmer conducted a classic s mated speed for the "smashed into" group? Use a college students watched a film of an automobile demonstrating how the language used to ask a ques- tion can influence eyewitness memory. In the study, accident and then were asked questions about what they saw. One group was asked, "About how fast were the cars going when they smashed into each other?" b. Compute the estimated value for Cohen's d to 81 92 study = 10 a = 85 = 160 = .01 group was asked the same question except Another the verb was changed to "hit" instead of "smashed into." The "smashed into" group reported signifi- cantly higher estimates of speed than the "hit" group.

Of the 46% who have children, 85% carry cash on a regular basis. Is carrying cash independent from having children in this sample? No, P(carry cash) = P(carry cash|have children). No, P(carry cash) ≠ P(carry cash|have children). Yes, P(carry cash) = P(carry cash|have children). Yes, P(carry cash) ≠ P(carry cash|have children).UCLA conducted a survey of more than 263,000 college freshmen from 385 colleges in fall 2005. The results of students' expected majors by gender were reported in The Chronicle of Higher Education (2/2/2006).

The results for males are shown in the table below. The second column in the table does not add to 100% because of rounding.Conduct a goodness-of-fit test to determine if the actual college majors of graduating males fit the distribution of their expected majors.

- A student researcher was surprised to learn that the 2017 NCAA Student-Athlete Substance Use Survey supported that college athletes make healthier decisions in many areas than their peers in the general student body. He collected data of his own, focusing exclusively on male student-athletes to see if such habits vary based on one’s sport. He asked 93 male student-athletes whether they had engaged in binge-drinking in the last month (> 5 drinks in a single sitting). Data are provided in the table below.

Fos co University provides housing for 10% of the gradua te students on campus. The housing office thinks that the percentage of graduate students looking for campus housing may be more than 10%. The office decides to survey a random sa mple of graduate students, and 62 of the 481 respondents say that they are looking for housing on campus. (a) With the results of the survey, would you recommend that the Fosco U niversity consider increasing the amount of housing on campus for graduate students? Give the appropriate evidence/test to support your dlaim. Use a significance level of.05. (b) In addition to the 481 graduate students who completed the survey, an additional 19 students did not respond. If the 19 responded, would you change your recommendation?
