- When I took the PRCA my scores were much high than the other two tests and I know that this test is essentially showing what my communication apprehension is like and I think that the reason that this test is much lower scored than all the others is because im just not really a communicative person. I do tend to find it at times hard to work with people and many times I would just much rather be tasked with doing something myself so I can get it done my way and I feel like that is just much more of an effective way for me to work on something. And knowing that I am already this way with people that are from a similar background with me then I am more inclined to not work well with people who are more different than that. I'm not unable to work with people I just prefer to work alone. And I had once worked with someone from a different cultural background and It just wasn't for me because I couldn't really understand them through their accent very well and it would frustrate me because…Jachuck et al. (1982) report on a drug designed to reduce hypertension (high blood pressure). Such hypotensive drugs are frequently effective but are also linked to side effects like irritability and a decline in energy. Seventy-five patients with mild hypertension were put on hypotensive drugs and their progress was monitored by doctors and spouses. When asked to rate the treated patients as improved, worse, or unchanged, the doctors rated all 75 patients as "improved." Meanwhile, the spouses rated 74 of the 75 patients as "worse." Why might spouses and doctors differ in their opinion about the effect of going on blood pressure medication?It is argued that government agencies force companies to give consumers information and this this will improve market efficiency. Group of answer choices a. true b. false
- q7- Which statement is incorrect for statistical independence between X and Y? Select one: a. The occurence of Y has no impact on the probability for the occurence of X b. If X and Y occur jointly, it is purely by chance c. The correlation between X and Y is 0 d. The correlation between X and Y is 1Pls answer all three question, pls explain the correct option in 5-6 sentences.Hansel has been making a cuckoo wristwatch, which he sells over the web. Customers are willing to pay $600 for Hansel’s watch, and each one costs him $240 to make. He has no fixed costs. Gretel is considering entry into this market. Her consultant has conducted a large-scale study of customers to determine how much they are willing to pay for watches of various quality levels. The consultant has found that customers’ willingness to pay equals 150q per watch, where q is a quality index the consulting firm has developed that ranges from 1 to 10. Gretel’s cost would be 15q2 per watch. Regardless of whether or not Gretel enters the market, and regardless of the quality level she chooses, Hansel will not change his competitive positioning. Suppose Gretel chooses to enter the market with a lower quality level to save on costs. Specifically, her quality index equals 3. What is her added value vis-à-vis Hansel (per watch)? What is the optimal quality level Gretel should choose…

- Here is a selection from an abstract of a recent study entitled “The effect of health insurance coverage on the use of medical services” by Michael Anderson, Carlos Dobkin, and Tal Gross (2010). NBER Working paper No. 15823. Substantial uncertainty exists regarding the causal effect of health insurance on the utilization of care. Most studies cannot determine whether the large differences in healthcare utilization between the insured and the uninsured are due to insurance status or to other unobserved differences between the two groups. In this paper, we exploit a sharp change in insurance coverage rates that results from young adults “aging out” of their parents insurance plans to estimate the effect of insurance coverage on the utilization of emergency department (ED) and inpatient services. [In the US, children are eligible for insurance coverage through their parents’ insurance only up to their 23rd birthday, at which point they lose eligibility.] Using the National Health…Indicate whether each statement is true or false, and justify your answer.There are several survey methods that health services researchers use to measure quality of life under different diseases.which of the following is the correct interpretation of the multicollinearity test?
