- 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 II error? A. A Type II 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 II 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 II error would occur if, in reality, the new needle reduces the incidence of…A medical device company has developed a new needle that they claim reduces the incidence of injection-site reactions for a particular medication.

Explain underwhat conditions the doctor would be committing a type Ierror and under what conditions he would be committinga type II error.
- When is a researcher at risk of making a type 2 error? whenever H0 is rejected whenever H1 is rejected whenever H0 fails to reject the risk of a type 2 is independent of the decision from a hypothesis testFind the Type II error given that the null hypothesis, H0, is: there are no more than 15% of structures in the county were built without permits.And, the alternative hypothesis, Ha, is: a building inspector claims that more than 15% of structures in the county were built without permits. Select the correct answer below: The building inspector concludes that more than 15% of the structures in the county were built without permits when, in fact, no more than 15% of the structures were built without permits. The building inspector concludes that more than 15% of the structures in the county were built without permits when, in fact, more than 15% of the structures were built without permits. The building inspector cannot conclude that more than 15% of the structures in the county were built without permits when, in fact, no more than 15% of the structures were built without permits. The building inspector cannot conclude that more than 15% of the structures in the county were…A group of scientist test the claim that hepititis C can live on a straw for longer than on a water bottle, on adverage. A) Write the null and alternative hypothesis. B) If the scientists commits a Type 1 error, write that error in context. C) If the scientist commits Type 2 error, write that error in context. D) If level of significance is 0.05 and the P-Value=0.017, write the conclution in context.
- The researcher was interested in examining whether there was a significant difference between (a) the placebo vs. the drug conditions (include all drugs here), (b) the old drugs vs. the new drugs, and (c) the new drugs (Drug C vs. Drug D). The question is: State the null and alternative hypotheses for each of the contrasts below.f our null hypothesis is H0: ? = 40, what are the three possiblealternative hypotheses?Determine whether the claim stated below represents the null hypothesis or the alternative hypothesis. If a hypothesis test is performed, how should you interpret a decision that (a) rejects the null hypothesis or (b) fails to reject the null hypothesis? A report claims that less than 80% of households in a specific county struggle to afford basic necessities. Does the claim represent the null hypothesis or the alternative hypothesis?
- To provide support for a hypothesis, one must a. reject the null hypothesis b. affirm the consequent c. accept the null hypothesis d. use very large samplesA Type I error is defined as a. rejecting a null hypothesis when it is in fact true b. rejecting a false null hypothesis c. failing to reject a true null hypothesis d. failing to reject a false null hypothesisA sample of eligible voters was selected to test if more than 60% of votes intend to vote in the election. The null and alternative hypotheses for this test are: Ho:p=.6 HA:p>.6 A.) choose from the following one that shows what happens if a type 1 error occurs. 1.) we conclude that 60% or less intend to vote in the election but, actually , more than 60% intend to vote in the election. 2.) we conclude that more than 60% intend to vote in the election but, actually, it is not true that more than 60% intend to. 3.) we conclude that 60% intend to vote in the election but, actually the % is lower than 60% 4.) none of the above is true. B.) choose from the following one that shows what happens if a type 2 error occurs. 1.) we conclude that 60% or less intend to vote in the election but, actually , more than 60% intend to vote in the election. 2.) we conclude that more than 60% intend to vote in the election but, actually, it is not true that more than 60% intend to. 3.) we…
