Suppose that there are two otherwise-identical vacation destinations, but one has a 0.2% greater risk of death due to a riskier airport and roads. The total price of a vacation in the more dangerous destination is $10,000 less than in the safer destination. Both vacation destinations are well-frequented, but not fully booked. All vacation- goers value their lives identically. What is the implied VSL (Value of Statistical Life) among these vacation-goers?

Which of the following individuals is likely to be excluded from a clinical trial?     An individual with other diseases besides the disease of interest.     An individual whose data is considered to be an outlier.     An individual of who is considered to be a minority.     An individual who will have difficulty complying trial protocols.

Most Australian youth-sports leagues separate athletes by birthdate, and the cutoff date is January 1st. Thus, those children born in January and February have some physical advantages in youth sports over those born in November and December. A recent studysuggests that those physical advantages enjoyed early in life impact the likelihood of a child becoming a professional athlete. The table gives the number of Australian-born 2009 Australian Football League players born in different months of the year, as well as the proportion of births expected if the birthdates of the athletes matched the distribution of all births nationally. Is there evidence that the distribution of birthdates of AFL athletes is not the same as the distribution of birthdates nationally?   Birthdates nationally in Australia and for Australian football players   Proportion Actual for Months Nationally AFL players Jan-Mar 0.248 196 Apr-June 0.251 162 Jul-Sep 0.254 137…

Tourism is extremely important to the economy of Florida. Hotel occupancy is an often-reported measure of visitor volume and visitor activity (Orlando Sentinel, May 19, 2018). Hotel occupancy data for February in two consecutive years are as follows. Current Year 1,476 1,800 Occupied Rooms Total Rooms 1,422 1,800 a. Formulate the hypothesis test that can be used to determine whether there has been an increase in the proportion of rooms occupied over the one-year period. Let P₁= population proportion of rooms occupied for current year P2 population proportion of rooms occupied for previous year - P2 less than or equal to 0 greater than 0 Ho P1 Ha P1 P2 b. What is the estimated proportion of hotel rooms occupied each year (to 2 decimals)? Current year .80 X Previous Year .77 c. Conduct a hypothesis test. What is the p-value (to 4 decimals)? Use Table 1 from Appendix B. Previous Year p-value = 0.0166 Using a 0.05 level of significance, what is your conclusion? We can conclude that there…

Here is the Statistics problem. Read this passage. What is the explanatory variable in this passage?

"Fruit Juice May Be Fueling Pudgy Preschoolers, Study Says" is the title of an article that appeared in the San Luis Obispo Tribune. This article describes a study that found that for 3- and 4-year-olds, drinking something sweet once or twice a day doubled the risk of being seriously overweight one year later. The authors of the study state the following. Total energy may be a confounder if consumption of sweet drinks is a marker for other dietary factors associated with overweight.t Give an example of a dietary factor that might be one of the potentially confounding variables the study authors are worried about. O Children who drink sweet drinks have stricter parents who let them eat and drink whatever they want. Children who drink sweet drinks have more lenient parents who track their weight and focus on their health more. O Children who drink sweet drinks may also drink less each day than other kids. Children who drink sweet drinks may also eat a lot of sweet foods and high-calorie…

In recent years there has been considerable controversy over the use of standardized testing of high school students. Supporters say that the practice is a good measure of both student progress and teacher performance. Opponents say that too much testing impedes learning and causes unnecessarily large expenses for the school districts. There are even reports that a significant number of high school students opt out of taking some of the standardized tests. In one large city where the school district reported that the average score on a national test taken by students in their junior year was 74, a large group of parents felt that this average was too low. The parents contracted a research company in an attempt to show that the average score was higher than the claimed average of 74. The research company took a random sample of 100 juniors and they collected the corresponding 100 exam scores for those students. - what hypotheses is most appropriate to deal with the problem above. - What…
