States (and provinces) that have control over taxation sometimes reduce taxes in an attempt to spur economic growth. Suppose that you are hired by a state to estimate the effect of corporate tax rates on, say, the growth in per capita gross state product (GSP).(i) What kind of data would you need to collect to undertake a statistical analysis?(ii) Is it feasible to do a controlled experiment? What would be required?(iii) Is a correlation analysis between GSP growth and tax rates likely to be convincing? Explain.
Researchers conducted a prospective cohort study to assess the association between dietary supplements and cognitive ability among children. A total of 500 children age 12-17 years who take an omega-3 fatty acid supplement are compared with 500 children age 12-17 years who do not take an omega-3 fatty acid supplement. Researchers follow the children for 2 years. During this time, 300 children who take the supplement earn what is classified as a “high” score on a cognitive test while 200 children who do not take the supplement earn what is classified as a “high” score on the same cognitive test. Show calculations.
a) Construct a 2x2 table from the information presented above
b) The risk difference is:
The results of Crum and Langer's hotel experiment:
Select one:
a.
were contradicted by the results of correlational research based on a student survey about health, diet, and exercise and personality measures.
b.
were discounted because the evidence was purely correlational.
c.
had little impact because the statistical analysis was flawed.
d.
provided additional support for the idea that people's beliefs and expectations can have a powerful influence.

(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.

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."
