- Does regular exercise reduce the risk of a heart attack? Provided are two ways to study this question. 1. A researcher finds 2000 men older than age 40 who exercise regularly and have not had heart attacks. She matches each with a similar man who does not exercise regularly, and she follows both groups for 5 years. 2. Another researcher finds 4000 men older than age 40 who have not had heart attacks and are willing to participate in a study. She assigns 2000 of the men to a regular program of supervised exercise. The other 2000 continue their usual habits The researcher follows both groups for 5 years. Select the correct explanation clearly detailing why the second design will produce more trustworthy data. a)select all that apply 1- In the second design, the subjects are chosen in a random fashion, whereas in the first design the subjects from the second group are matched to the subjects in the first group. 2-The first design is an observational study whereas the second design is an…please answer for the 2nd, 4th, 8th and 16th days Need only a handwritten solution only (not a typed one).A research wants to determine if pre-natal exposure to the hormones in birth control pills alters the sex makeup of midshipman fish populations (which are typically half male and half female).Specifically, the researcher wishes to test the hypothesis that exposure to hormones will increase the number of females in the population.The researcher exposes a group of pregnant midshipman fish to birth control hormones and records the sex of the first 19 offspring birthed.They then observe that 0 are female.Use a sign test to test the indicated hypothesis.What is the obtained value?

The scores of individual students on a national test have a normal distribution with mean 18.6 and standard deviation 5.9. At Columban College, 76 students took the test. If the scores at this school have the same distribution as national scores, what are the mean and standard deviation of the sample mean for 76 students.

- A salon owner estimates the number of clients she is expecting during the festive season to be 20% during Monday to Wednesday, 20% on Thursday and 60% over the weekend. She therefore hires additional staff to assist during the weekend to meet the client demand. She however only observes 30% during Monday to Wednesday, 20% on Thursday and 50% over the weekend in the first week of December. The salon owner is uncertain whether she should reduce the planned staff for the December festive period due the observed trend or not. She conducts a statistical test at α = 0.05 to determine if the observed trend fits the expected trend. Which of the following statements is true? A. The conclusion of the test is that she should not keep the additional staff for the weekend. B. The df for this test is 3. C. The p-value is greater than α. D. The null hypothesis is that the observed trend is different to the expected trend. E. The test statistic is χ2 = 5.33.In a classic study of problem solving, Duncker (1945) asked participants to mount a candle on a wall in an upright position so that it would burn normally. One group was given a candle, a book of matches, and a box of tacks. A second group was given the same items, except that the tacks and the box were presented separately as two distinct items. The solution to this problem involves using the tacks to mount the box on the wall, creating a shelf for the candle. Duncker reasoned that the first group of participants would have trouble seeing a new function for the box (a shelf) because it was already serving a function (holding tacks). For each participant, the amount of time to solve the problem was recorded. Data similar to Duncker’s are as follows. Time to Solve Problem (in sec.) Box of Tacks Tacks and Box Separate 128 42 160…Researchers are interested in seeing how likely adolescents are to return money that doesn't belong to them. In order to investigate this, they tell participants they are studying performance on math tests. Once a participant arrives, a member of the research team leads the participant into a lab room with a one-way mirror and asks the participant to wait for a few minutes while the researcher gets the math test. As the researcher leaves the room, they "accidentally" drop a $50 bill on the floor. In room next door, the researchers watch the participant through the one-way mirror for 5 mins to see if they pick up the money. When the researcher re-enters the lab room 5 minutes later with the math test, they make no mention of dropping the money. The researchers then record if the participant returns the money. Which of the following help prevent demand characteristics from interfering with the way the participant behaves in this study? A: The researcher "accidentally" dropping the money…
- There are several risks and costs associated with the airline's decision to overbook flights. If too many passengers show up, the airline may need to offer incentives for customers to give up their seats, which can be costly. If too few passengers show up, the airline may be forced to fly with empty seats, resulting in lost revenue. Furthermore, overbooking can lead to negative publicity and damage to the airline's reputation if too many customers are bumped from their flights. In terms of strategy, the airline must weigh the potential benefits of overbooking (maximizing revenue by filling as many seats as possible) against the potential risks and costs. The airline may also consider adjusting its overbooking policy based on factors such as the route, time of day, and historical data on no-show rates for specific flights. Overall, effective demand forecasting and capacity planning are crucial for the airline to optimize its operations and profitability while minimizing negative…In a study carried out among low-income families in the young towns of Detroit, it was found that 30% spent less than $8 weekly on purchasing charcoal and consumed products from soup kitchens. 35% spent $8 to $15 weekly on the purchase of charcoal. 5% spent more than $15 weekly on the purchase of charcoal and consumed products from the soup kitchen. 15% spent more than $15 each week buying coal. Finally, 55% did not consume the products of the soup kitchens.If you randomly choose a low-income familyto. What is the probability that you spend less than $8 weekly on purchasing coal?b. What is the probability that you do not consume the products of the soup kitchens and spend 8 to 15 dollars buying charcoal?C. If the family spends more than $15 weekly on purchasing charcoal, what is the probability that they will not consume the products from the soup kitchens?d. If the family does not consume products from soup kitchens, what is the probability that it will spend less than 8 soles per…Many states mandate tests that have to be passed in order for the students to graduate with a high school diploma. A local school superintendent believes that after-school tutoring will improve the scores of students in his district on the state's graduation test. As a trial run, a tutor agrees to work with 15 students for a month. The superintendent ask the school board to implement this after-school tutoring program if there is evidence that student scores would increase by an average of more than 20 points. Create a 95% confident level to estimate the true score increase. 25.4 23.3 17.8 21.3 14.8 28.8 22.5 23.6 32.3 15.4 23.4 27.5 18.8 19.1 20.4 a. Confidence Interval b. Conclusion
