    A homeowner thinks she may need a new roof. Because of costs, she wants to be sure a new roof is really needed before having the current one replaced. What is the homeowner's null hypothesis and what would be a type 1 error? a) H0: A new roof is not needed. A type 1 error would occur if she had a new roof put when it was not needed. b) H0: A new roof is needed. A type 1 error...

    Medical personnel are required to report suspected cases of child abuse. Because some diseases have symptoms that mimic those of child abuse, doctors who see a child with these symptoms must decide between two competing hypotheses: H0: symptoms are due to child abuse H1: symptoms are due to disease (Although these are not hypotheses about a population characteristic, this problem illustrates the definitions of Type I and Type II errors.) The article “Blurred Line Between Illness, Abuse Creates Problem for...

    Let μ denote the true average radioactivity level (picocuries per liter). The value 5 pCi/L is considered the dividing line between safe and unsafe water. Would you recommend testing H0: μ = 5 versus Ha: μ > 5 or H0: μ = 5 versus Ha: μ < 5? Explain your reasoning. [Hint: Think about the consequences of a type I and type II error for each possibility.] ---One should test H0: μ = 5 versus Ha: μ < 5.A type...

    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...

In a sense, the doctor is using a null and an alternative hypothesis to decide whether or not to administer treatment. The hypotheses might be stated as: Ho: The person does not have arthritis and Hy: The person has arthritis. Which of the following statements represents the doctor making a Type II...
