Will people spend less on health care if their health insurance requires them to pay some part of the cost themselves? An experiment on this issue asked if the percentage of medical costs that is paid by health insurance has an effect both on the amount of medical care that people use and on their health.

A health insurance company knows that there are two types of customers (smokers and non-smokers), each facing different health risks. The probabilities of getting sick and the healthcare costs in the case of illness for the two customer types is given in the table below. Group Healthcare costs Probability of getting sick Smokers $1200 50% Non-smokers $1200 20% Assume that each customer has a monthly income of $1600 and has a utility function given by U(x)=sqrt(x), where x is the...
Quit Smoking: The New England Journal of Medicine published the results of a double-blind, placebo-controlled experiment to study the effect of nicotine patches and the antidepressant bupropion on quitting smoking. With the data from the experiment we calculate the sample difference in the "quit smoking" rates for the nicotine treatment group and the placebo group ("treatment" minus "placebo"). We get 0.8% = 0.008. Which of the following is an appropriate conclusion based on this finding? A. In this experiment the...

The difference between the two instructional strategies is meaningful. c. It is likely one instructional strategy is more effective. d. Both instructional strategies are equally effective.

A team of researchers is investigating a drug for reducing systolic blood pressure. Two groups each has 6 subjects were selected in this study. Group A is the control group. The treatment was used for group B. A fixed increased amount of doses were used on group C. The systolic blood pressures were measured for all groups and are listed below. This team wishes to test whether there is a statistically significant difference in average systolic blood pressures between the...
