Blood pressure Diastolic blood pressure in adults is normally |distributed with µ = 80 mm Hg and o = 12 mm Hg. In a ran- dom sample of 300 adults, how many would be expected to have a diastolic blood pressure below 70 mm Hg?
Please do not give solution in image format thanku Suppose that the 4‐year graduation rate at a large, public university is 70 percent (this is the population proportion of successes). In an effort to increase graduation rates, the university randomly selected 300 incoming freshman toparticipate in a peer‐advising program. After 4 years, 222 of these studentsgraduated. Can you conclude that this program was a success at the 5‐percentlevel of significance?
In a famous study done in the 1960s two dolphins, Doris and Buzz, were trained to work together to earn fish. Doris was shown a light underwater. If the light was on steadily, her partner Buzz on the other side of the tank needed to press a button on the right for them to earn fish. If the light was blinking, he needed to press a button on the left. At one point in the study, the researcher hung a canvas in the middle of the tank in such a way that Buzz could not see the light. After looking at the light, Doris "swam near the curtain and began to whistle loudly. Shortly after that Buzz whistled back and then pressed the [correct] button". (Tintle, Rossman and Chance, MAA Prep Workshop) Of course, getting it right once was not enough to convince the scientists that there was really communication going on. It turned out, that in 15 out of 16 trials the dolphin pushed the correct button. Of course, it is possible that this happened just out of random chance - that the second dolphin just…

A researcher selected 100 passengers from each of 3 airlines and asked them if the airline had lost their luggage on their last flight.The number of passengers who lost luggage at airline 1 is 2, airline 2 is 14 and airline 3 is 1 You want to test the daim that the proportion of passengers from each airline who lost luggage an the flight is the same for each airline. What is the value of test statistic? Your answer: O chi^2 0 -21.15 O chi^2 0 10.77 O chi^2_0 =19.58 Ochi^2 0 =13.31 chi^20 =16.25 Clear answer
