Discuss what is meant by Type I and Type II errors in hypothesis testing.
Homework Answers
Type I error occurs due to incorrect rejection of null
hypothesis. The result might have been obtained due to some other
factor and not from the factor we are experimenting leading to
false cause and effect explanation.
Type II error occurs when one accepts the null hypothesis even
though it is incorrect.It fails to identify the actual hypothesis
and rejects it,

The notion of Type I and Type II Errors is very important in hypothesis testing. The Ho/Ha should be set up such that a Type I Error is more serious than a Type II Error. A common example used to discuss Type I and Type II errors is the example of a trial in the US. Under US law, a defendant is considered "innocent until proven guilty." You could set up this hypothesis test as follows: Ho: defendent is...

A 2 sided Confidence Interval for the mean is, in analogy to the 2-sided hypothesis test, a range of values under which you would fail to reject the null hypothesis By rewriting this statement about the rejection region, under the assumption the null hypothesis is true: into a statement about the interval for μ you construct the 2-sided...

In §9.2 the concepts of Type I and Type II errors are introduced. Consider the situation where a husband and wife go to the doctor’s office to each get some tests run and the doctor accidentally mixes up their charts. The doctor comes into the exam room with the results of the tests and declares that the wife is NOT pregnant but her husband IS indeed pregnant with a baby. How does this illustrate the concepts behind Type I and...

What would be Type I or Type II errors in these scenarios: If a consumer group wants to see if people can tell whether they are drinking tap water or bottled water would this create a Type I or Type II error? If a college instructor wishes to see whether his students prefer to work on assignments individually or in groups would a Type I or Type II error occur? If a teacher is evaluating a program designed to improve...
