A doctor is asked to give an executive a thoroughphysical checkup to test the null hypothesis that he will beable to take on additional responsibilities. Explain underwhat conditions the doctor would be committing a type Ierror and under what conditions he would be committinga type II error.

Suppose a researcher comes up with a new drug that treats Borderline Personality Disorder (BPD). She assigns some patients who have BPD to receive a placebo and others to receive the new drug. The null hypothesis is that the drug will have no effect. 1. In this case, what would be the Type I error?  In this case, what would be the Type II error?

A medical device company has developed a new needle that they claim reduces the incidence of injection-site reactions for a particular medication. An experiment is to be conducted to determine if there is sufficient evidence to make that claim. Which of the following is a correct description and consequence of a Type I error? A. A Type I error would occur if the medical device company incorrectly administers the medication with the new needle, causing it to be impossible to determine whether the number of injection-site reactions have increased or decreased with the new needle.  B. A Type I error would occur if, in reality, the new needle does not reduce the incidence of injection-site reactions, but the significance test detects such a difference. The consequence of such an error would be that the medical device company would produce this new needle, but it would not be beneficial. C. A Type I error would occur if, in reality, the new needle reduces the incidence of injection-site…

Christine, a researcher in psychology and biobehavioral health, believes that city residents and residents of rural areas differ in how appealing they find owning a cat. A random sample of 109 people who live in San Antonio were surveyed and 59 identified themselves as a "cat person." A random sample of 108 people who live in the surrounding rural area were selected and 72 identified themselves as a "cat person." Conduct an appropriate hypothesis test at the a = 0.1 significance level to test Christine's claim. Round answers to 4 decimal places where appropriate. a. State the null and alternative hypotheses.
