It is estimatedthat 0.9143 of Scottish farmers who receive thebrochure possess enough information to deal with anoutbreak of the disease, but only 0.815 of those withoutthe brochure can deal with an outbreak. After the firstthree months of mailing, a ratio of the farmers inScotland received the informative brochure. Find theratio of the farmers in Scotland who received theinformative brochure if the probability that a randomlyselected farmer will not have enough information to dealeffectively with an outbreak of the disease is 0.1019852.Select one:a. 0.83600000b. 0.81500000O c. 0.91430000O d. 0.16400000O e. 0.18500000O f. 0.08570000Quiz 2Previous pageNext pageJump to...

4. Straight As now, healthy later A study by Pamela Herd of the University of Wisconsin-Madison found a link between high-school grades and health. Analyzing data from the Wisconsin Longitudinal Study, which has tracked the lives of thousands of Wisconsin high-school graduates from the class of 1957, Herd found that students with higher grade-point averages were more likely to say they were in excellent or very good health in their early 60s. Does this mean people will live healthier lives if they increase their GPA? Explain.47

Sleep apnea is a condition in which the sufferers stop breathing momentarily while they are asleep. This condition results in lack of sleep and extreme fatigue during waking hours. A current estimate is that 16.3 million out of the 312.7 million Americans suffer from sleep apnea, or approximately 5.2%. A safety commission is concerned about the percentage of commercial truck drivers who suffer from sleep apnea. They do not have any reason to believe that it would be higher or lower than the population’s percentage. To test the claim that the percentage of commercial truck drivers who suffer from sleep apnea is not 5.2%, a simple random sample of 380380 commercial truck drivers is examined by a medical expert, who concludes that 29 suffer from sleep apnea. Does this evidence support the claim that the percentage of commercial truck drivers who suffer from sleep apnea is not 5.2%? Use a 0.01 level of significance. Step 1 of 3 : State the null and alternative hypotheses for the test.…
