- This is a hypothetical question: You run an RCT and there is imperfect compliance. In general, if you compare the people who actually received treatment to people who didn’t, will you recover the causal effect of treatment? Explain. Is there a situation where if you make this comparison that you would recover the causal effect? Is so, what is it? If not, why not? Thank you very much!A hypothetical study looks at the effect of drinking alcohol on health. Across all genders and age groups, people who do not drink tend to be healthier on average than people who do drink. However, people who drink regularly are on average healthier than those people who have recently stopped drinking. Is it reasonable to conclude that for the sake of health, we should not start drinking, but if we have already started drinking alcohol, it is healthier to continue and not to stop?Study 1: A study of 300 high school students was done. Half of them were instructed to drink soda every day. The other half was instructed to not drink soda at all. After one month, the half that were drinking soda had gained an average of five pounds more than the half that did not drink soda. e. How could this study be changed to make it a double-blind study?
- More and more households are struggling to pay utility bills given high heating costs. Particularly hard hit are households with homes heated with propane or heating oil. Many of these households are spending twice as much to stay warm this winter compared to those who heat with natural gas or electricity. A representative sample of 500 households was taken to investigate if the type of heating influences whether or not a household is delinquent in paying its utility bill. The following table reports the results. (see image attached) a. What is the probability that a randomly selected household uses heating oil? b. What is the probability that a randomly selected household is delinquent in paying its utility bill? c. What is the probability that a randomly selected household uses heating oil and is delinquent in paying its utility bill? d. Given that a household uses heating oil, what is the probability that it is delinquent in paying its utility bill? e. Given that a household is…Question 10In the Preview for this Chapter, we discussed a study by McGee and Shevlin (2009) demonstrating that an individual’s sense of humor had a significant effect on how the individual was perceived by others. In one part of the study, female college students were given brief descriptions of a potential romantic partner. The fictitious male was described positively and, for one group of participants, the description also said that he had a great sense of humor. Another group of female students read the same description except it now said that he has no sense of humor. After reading the description, each participant was asked to rate the attractiveness of the man on a seven-point scale from 1 (very unattractive) to 7 (very attractive) with a score of 4 indicating a neutral rating. a. The females who read the “great sense of humor” description gave the potential partner an average attractiveness score of M = 4.53 with a standard deviation of s = 1.04. If the sample consisted of n = 16…
- You are concerned that nausea may be a side effect of Tamiflu, but you cannot just give Tamiflu to patients with the flu and say that nausea is a side effect if people become nauseous. However, past research indicates that about 30% of people who get the flu experience nausea, and you believe that the percentage of those who experience nausea while having the flu and taking Tamiflu will be greater than 30%, which would indicate that nausea is a side effect of Tamiflu.a) If you going to test this claim at the 0.05 significance level, what would be your null and alternative hypotheses?H0H0: H1H1: b) What type of hypothesis test should you conduct (left-, right-, or two-tailed)? left-tailed right-tailed two-tailedYou are concerned that nausea may be a side effect of Tamiflu, but you cannot just give Tamiflu to patients with the flu and say that nausea is a side effect if people become nauseous.

Note that one mean is not given. Which value for the missing mean would most clearly result in an AxB interaction? B1 B2 A1 50 30 A2 60 ? a. M = 80 b. M = 40 c. M = 50 d. M = 60Question 2: Two opposing provincial members of parliament are debating the merits of increasing funding for education. The member representing the opposition party claims that additional funding will reduce failure rate, while the governing member maintains that this is not evident. The opposition member presents the following data to support her claim, taken from eight cities in the province. 5.2 7.3 3.5 Operating Budget (millions/year) Number of graduates | (hundreds) 9.8 16.4 2.8 6.6 6.1 13 16 11 25 74 8.5 17 15 Perform a two-variable data analysis to determine if increased funding for education will reduce the failure rate. Note: Use excel or google sheets only to create graphs and calculations. The following should be included in your answer: • Scatter plot(s) including line of best fit and correlation coefficient. • Classification of the linear correlation and type of causal relationship. Extraneous variables that may affect either variable. Any possible bias? • Does your…
