When doing hypothesis testing in the real world • A. the researcher knows when the effects are real, but does not know when they are not real. • B. the researcher rarely knows the population parameters • C. the researcher knows when he or she has made a Type I error. • D. the researcher knows when he or she has made a Type II error.
Homework Answers
For doing the hypothesis testing in the real world under a given level of significance the researcher can know the probability of making a type I or type I error but not know when they have made it.
in the real world they rarely know the population parameters because the population concerned is very large and it is nearly impossible to sample the whole population.
So option B is correct.

The term "error" is used two different ways in hypothesis testing: 1) Type I error (or Type II) and 2) standard error. What can a researcher do to influence the size of the standard error? Does this action have any effect on the probability of a Type I error? What can a researcher do to influence the probability of a Type I error? (4 points)

You are testing the null hypothesis µ=150 versus the two tailed alternative. You reject the null hypothesis in favor of the alternative hypothesis. If in reality, µ does equal 150, you have made a : A. Correct Decision B. Type II Error C. Type I Error

1) After a scientist conducts research and reaches a conclusion about the null hypothesis, is there any way for the scientist to know if he/she has made either a Type I or Type II error? If there is a way for the scientist to know, explain what that is and how it will show the scientist if he/she made either type of error. If there is NOT a way for the scientist to know, explain why not. NOTE: When giving...

6. Which of the following statements about hypothesis testing are true? • A type I error occurs if H, is rejected when it is true. • A type II error occurs if He is rejected when it is true. • The power of a test is the probability of failing to reject H, when it is false.

ESAND ABUSES 1 Uses Hypothesis Testing Hypothesis testing is important in many different fields because it gives a scientific procedure for assessing the validity of a claim about a population. Some of the concepts in hypothesis testing are intuitive, but some are not. For instance, the American Journal of Clinical Nutrition suggests that eating dark chocolate can help prevent heart disease. A random sample of healthy volunteers were assigned to eat 3.5 ounces of dark chocolate each day for 15...
