- 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 testWhat values of F indicate that the null hypothesis is true?Which of the following is the value necessary for rejection (or nonacceptance) of the null hypothesis? 1. The critical value 2. The obtained value 3. Type I error 4. Type II error
- additionally does this reject the null hypothesisFind 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…What does the chi-square test of independence test for? Option C is not correct. if the two variables combine or influence each other if the two variables are significantly different from each other if the two variables tested are both dependent on the frequencies if the two variables are significantly similar to each other
- Based on this p value can we reject the null hypothesis??A Chi square test has been conducted to assess the relationship between marital status and church attendance. The obtained Chi square is 7.45 and the critical Chi square is 9.488. What may be concluded? Group of answer choices A.reject the null hypothesis, church attendance and marital status are independent B.fail to reject the null hypothesis, church attendance and marital status are independent C.Reject the null hypothesis, church attendance and marital status are dependent D.fail to reject the null hypothesis, church attendance and marital status are dependentIf the decision rule for a one-tailed test of hypothesis is given as: Reject Ho if z<-2.36. What is the value of alpha?
- An airline wants to test the null hypothesis that 60percent of its passengers object to smoking inside the plane. Explain under what conditions they would be com-mitting a type I error and under what conditions they would be committing a type II error.The probability of the data under the model of the alternative hypothesis (model 1) is 0.0008 and that of the model of the null hypothesis (model 0) is 0.400. What is the value of the Bayes Factor (BF01)?If a null hypothesis is rejected at the 0.05 level of significance, it must be rejected at the 0.01 level. True or False?
