In the context of hypothesis testing, which of the following statements is correct regarding Type I and Type IIerrors?a) A Type I error occurs when you reject the null hypothesis when it is true, and a Type II error occurs when youfail to reject the null hypothesis when it is false.b) A Type I error occurs when you fail to reject the null hypothesis when it is true, and a Type II error occurs whenyou reject the null hypothesis when it is false.c) Type I and Type II errors are mutually exclusive and cannot occur simultaneously in a single test.d) Type I error is directly related to the power of the test, while Type II error is related to the significance level.

(d) Decide whether to reject or fail to reject the null hypothesis. O A. Fail to reject H, because the test statistic is in the rejection region(s). O B. Reject H, because the test statistic is not in the rejection region(s). O C. Fail to reject Ho because the test statistic is not in the rejection region(s). D. Reject Ho because the test statistic is in the rejection region(s). (e) Interpret the decision in the context of the original claim. A. At the 5% level of significance, there is sufficient evidence to reject the claim that the mean price is $24,000. B. At the 5% level of significance, there is not sufficient evidence to reject the claim that the mean price is $24,000. C. At the 5% level of significance, there is sufficient evidence to reject the claim that the mean price is not $24,000. O D. At the 5% level of significance, there is not sufficient evidence to reject the claim that the mean price is not $24,000.
If we fail to reject (i.e., "accept") the null hypothesis, does this mean that we have proved it to be true beyond all doubt? Choose one of the options: A. No, it suggests that the evidence is not sufficient to merit rejecting the null hypothesis. B. No, it suggests that the null hypothesis is true only some of the time. C. Yes, if we fail to reject the null we have found evidence that the null is true beyond all doubt. D. Yes, it suggests that the evidence is sufficient to merit rejecting the alternative hypothesis beyond all doubt.
When using the 4 step hypothesis testing method, the alternative hypothesis __________? a. is symbolized by: H1 b. is symbolized by: H0 c. states that the two population means are equal d. must be directional in nature (must be a one tailed test)
(a) Express the null hypothesis and the alternative hypothesis in symbolic form for the following claim. A manager claims that the average lunch break is more than 0.4 hours long. O Ho: p = 0.4 vs. H: p 0.4 H;: µ # 0.4 O Ho: H = 0.4 vs. H: µ > 0.4 O Ho: p = 0.4 Hi:p # 0.4 Vs. (b) State the indicated conclusion in nontechnical terms, being sure to address the original claim. An entomologist writes an article in a scientific journal claiming that at most 1.48% of male fireflies are unable to produce light due to a genetic mutation. A hypothesis test of the claim has been conducted, and the decision from that test is to fail to reject Ho. O There is not sufficient evidence to warrant rejection of the claim that the true proportion is at most 1.48%. O There is sufficient evidence to warrant rejection of the claim that the true proportion is at most 1.48%. OThere is not sufficient evidence to support the claim that the true proportion is at most 1.48%. O There is sufficient evidence to…
5. Possible outcomes of a hypothesis test The following table depicts the four possible outcomes of a hypothesis test: The researcher makes a correct decision [either by correctly rejecting the null hypothesis (H₀) or correctly not rejecting the null hypothesis], makes a Type I error, or makes a Type II error. In each of the following boxes, select the description that matches the outcome. Decision Truth H₀ False H₀ True Reject H₀ Outcome A Outcome B Do not reject H₀ Outcome C Outcome D The probability of a Type I error is , and the probability of a Type II error is .
If a researcher fails to reject the null hypothesis, he or she can conclude that: Question 35 options: the null hypothesis is true. the alternative hypothesis is true. there is adequate evidence to reject the null. there is no adequate evidence to reject the null.
Assume that adults were randomly selected for a poll. They were asked if they "favor or oppose using federal tax dollars to fund medical research using stem cells obtained from human embryos." Of those polled, 484 were in favor, 397 were opposed, and 123 were unsure. A politician claims that people don't really understand the stem cell issue and their responses to such questions are random responses equivalent to a coin toss. Exclude the 123 subjects who said that they were unsure, and use a 0.10 significance level to test the claim that the proportion of subjects who respond in favor is equal to 0.5. What does the result suggest about the politician's claim? Identify the null and alternative hypotheses for this test. Choose the correct answer below. А. Но: р3D0.5 H4:p>0.5 В. Но: р#0.5 H1:p= 0.5 С. Но: р-0.5 H1:p<0.5 D. Ho: p= 0.5 H1:p#0.5 Identify the test statistic for this hypothesis test. The test statistic for this hypothesis test is. (Round to two decimal places as needed.)…
A type Il error A. arises when the false null hypothesis is not rejected. O B. is the rejection of a false null hypothesis. C. arises when the true null hypothesis is not rejected. D. is the rejection of a true null hypothesis.

View the information below and respond accordingly. When you perform a hypothesis test, there are four possible outcomes depending on the actual truth (or falseness) of the null hypothesis H0 and the decision to reject or not. The outcomes are summarized in the following table: Table 9.2 ACTION H0 IS ACTUALLY True H0 IS ACTUALLY False Do not reject H0 Correct Outcome Type II error Reject H0 Type I Error Correct Outcome
