Suppose you have a hypothesis test which never rejects the null hypothesis, no matter the value of the test statistic. Name a potential problem with such a test. Select one: a. There can be no problem with such a hypothesis test, this is the ideal scenario. b. Using this test would lead to making an excessive number of Type I errors. c. Using this test would lead to making an excessive number of Type II errors.

Esp A college professor states that this year's entering students appear to be smarter than entering students from previous years. The college's records indicate that the mean IQ for entering students from earlier years is 110. Suppose that we want to sample a small number of this year's entering students and carry out a hypothesis test to see if the professor's statement can be supported. State the null hypothesis H, and the alternative hypothesis H, that we would use for this test. Ho: 0 H: [ O
A Type I error is: Select one: incorrectly specifying the null hypothesis. accepting the null hypothesis when it is false. rejecting the null hypothesis when it is true. incorrectly specifying the alternative hypothesis.
A snack food company produces a 454g bag of pretzels. Although the actual net weights deviate slightly and vary bag to bag, the company insists that the mean net weight of the bags to be 454g. Determine the null and alternate hypothesis as well as the classification of the hypothesis test as left, right, or two tailed.
A researcher claims that the proportion of students who have traveled abroad is greater than 45%. To test this claim, a random sample of 750 students is taken and its determined that 374 students have traveled abroad. The following is the setup for this hypothesis test: Ho : p-0.45 Ha :p>0.45 In this example, the p-value was determined to be 0.004 come to a conclusion and interpret the results for this hypothesis test for a proportion (use a significance level of 5%) Select the correct answer below: The decision is to reject the Null Hypothesis. The conclusion is that there is enough evidence to support the claim The decision is to fail to reject the Null Hypothesis. The conclusion is that there is not enough evidence to support the claim
A man is on trial accused of murder in the first degree. The prosecutor presents evidence that he hopes will convince the jury to reject the hypothesis that the man is innocent. This situation can be modeled as a hypothesis test with the following hypotheses: Explain the meaning of a Type I error.
Suppose you have a hypothesis test which never rejects the null hypothesis, no matter the value of the test statistic. Name a potential problem with such a test. Select one: O a. Using this test would lead to making an excessive number of Type Il errors. O b. There can be no problem with such a hypothesis test, this is the ideal scenario. O c. Using this test would lead to making an excessive number of Type l errors.
Which of the following is an example of a Type 1 error? Rejecting a false null hypothesis. Rejecting a true null hypothesis. Failing to reject a false null hypothesis. Failing to reject a true null hypothesis.
You complete a hypothesis test using α = .05, and based on the evidence from the sample, your decision is to fail to reject the null hypothesis. If the treatment actually does NOT have an effect, which of the following is true? Group of answer choices You have made a Type II error. You have made the correct decision. You might have made a Type I error, but the probability is only 5% at most. You have made a Type I error.
A medical researcher claims that 70% of people pay for prescriptions with private insurance, 25% pay with Medicare, and the remaining pay with personal funds. To evaluate this claim, a random sample of 50 people was taken. The sample had the following results: Private Insurance Medicare Personal 32 10 8 What is the null hypothesis for the test? Enter the null hypothesis in the first blank. You do NOT need to enter the alternative hypothesis. Calculate the test statistic for the test and enter it in the second blank. Round your final answer to three decimals. Find the critical value cutoff for the rejection region and enter it in the third blank. Use alpha = 0.005.
Which is the correct null hypothesis based on this statement: People with diabetes have higher systolic blood pressure than people without diabetes? People with diabetes have lower systolic blood pressure than people without diabetes. People with diabetes have equal systolic blood pressure when compared to people without diabetes. People with diabetes have a systolic blood pressure equal to or lower than people without diabetes. None of these are a null hypothesis.
A medical researcher claims that the proportion of people taking a certain medication that develop serious side effects is 12%. To test this claim, a random sample of 900 people taking the medication is taken and it is determined that 93 people have experienced serious side effects.. The following is the setup for this hypothesis test: Ho :p 0.12 Ha p 0.12 In this example, the p-value was determined to be 0.124. come to a conclusion and interpret the results for this hypothesis test for a proportion (use a significance level of 5%) Select the correct answer below: The decision is to reject the Null Hypothesis. The conclusion is that there is enough evidence to reject the claim O The decision is to fail to reject the Null Hypothesis. The conclusion is that there is not enough evidence to reject the claim
Samples of Republicans, Democrats, and Independents have been tested for their level of support for welfare reform and the null hypothesis has been rejected. What may we conclude? a. the difference is significant, there are differences between the parties on this issue b. the difference is significant, the parties are the same on this issue c. the difference is not significant d. a Type I error hoc
