An epidemiologist is planning a case-control study to study the associationbetween farm residence exposure among pregnant women and childhood braincancer. Approximately 25% of mothers in the proposed study area live on a farm.Based upon the incidence rate for childhood brain cancer, the investigatoranticipates enrolling 100 case mothers and 100 control mothers. A comparablestudy recently conducted in another country reported a 2-fold odds ratio (OR) forchildhood brain cancer given maternal farm residence during pregnancy. Theinvestigator would like to ascertain if her/his sample size would be sufficient toachieve at least 80% power to detect a 2-fold or greater OR for childhood braincancer for the proposed study.

O Lumen OHM A https://ohm.lumenlearning.com/assess2/?cid%3D48367&aid%33500530#/skip/5 Suppose you play a die-rolling game in which a fair 6-sided die is rolled once. If the outcome of the roll (the number of dots on the side facing upward) is odd, you win as many dollars as the number you have rolled. Otherwise, you lose as many dollars as the number you have rolled. Let X be the profit of the game or the amount of money won or lost per roll. Negative profit corresponds to lost money. (a) What is your profit of the outcome if the roll is 6? 24 (b) Fill out the following probability distribution table. (Round your answers to two decimal places). Outcome Probability (c) Compute the expected value (the mean) of X. (Round your answer to the nearest hundredth.) (d) Explain the meaning of the expected value of X in the context of this problem.

In a small town in New York, we initiated a cohort study and followed 5,900 people for a mean follow-up of 2 years. At the end of the 2nd year, none of the participants was lost to follow-up. During this follow-up, we identified 600 cases of Covid-19. What was the cumulative incidence? O 10 cases O 10.1% O 50.8% O 10.1 per 1,000

Data originally from DASL http://lib.stat.cmu.edu/DASL/Datafiles/CancerSurvival.html (Links to an external site.). Some bronchial cancer patients had the following survival times (in days) after receiving a certain treatment: 20, 37, 63, 64, 72, 81, 138, 151, 155, 166, 166, 223, 245, 246, 450, 459. (The second instance of “166” is not a mistake.) Do these numbers suggest that the average survival time, for all bronchial cancer patients who receive that treatment, is significantly different from 200 days? CANCER SURVIVAL Report an appropriate one-sample hypothesis test and use a 10% significance level. For Step 5 of the six-step process that was taught in this class, which would be the appropriate procedure and why? Choose the correct option. Group of answer choices We would do a t-procedure because we have the standard deviation. We would do a t-procedure because the sample size is large. We would do a t-procedure because we do not have the population standard deviation and…
