If we reject the null hypothesis, we conclude that:
there is enough statistical evidence to infer that the alternative hypothesis is true. |
there is not enough statistical evidence to infer that the alternative hypothesis is true. |
there is enough statistical evidence to infer that the null hypothesis is true. |
there is not enough statistical evidence to infer that the null hypothesis is true. |
If we reject the null hypothesis, we conclude that: there is enough statistical evidence to infer...
A Type II error occurs in hypothesis testing when we _____________________________. fail to reject the null hypothesis and the null hypothesis is not true reject the null hypothesis and the null hypothesis is true fail to reject the alternative hypothesis and the alternative hypothesis is not true reject the alternative hypothesis and the alternative hypothesis is true
O A. Because the p-value is less than a, we reject the null hypothesis and conclude that the average det load is equal to $17,000 O B. Because the p-vakus is greafer than a we fail to reject the nu ○ C. Because the p-value is greater than a we fail to reject the nul hypothesis and cannot co clude that he OD. Because the pvalue is lesse an Suppose that the Department of Education would like to test the...
11. If we reject the null hypothesis, what can we conclude, subject to the probability, α? Multiple Choice Reject the null with a probability, α, of making a Type I error. The alternative hypothesis is false. The null hypothesis is true. Both the null hypothesis and the alternative hypothesis are true. 12. The average cost of tuition and room and board at a small private liberal arts college is reported to be $8,500 per term. A financial administrator believes that...
What can you conclude if we fail to reject the null hypothesis for two individual variables, but reject the null hypothesis for the two joint variables?
compute the test value. Does is reject the null hypothesis and is there enough evidence to support the claim that the average commute in his city is less than 25.4 Question 2 of 3 (1 point) View problem in a pop-up 8.3 Section Exercise 10 The National Novel Writing Association states that the average novel is at least 50,000 words. A A particularly ambitious writing club at a college-preparatory high school had randomly selected members with works of the following...
If we reject a null hypothesis, should we state that we have proved the alternative hypothesis to be true? Briefly explain why or why not.
A type I error is where we reject a true null hypothesis (Ho). a. True b. False A type II error is where we fail to reject a false null hypothesis (Ho). a. True b. False A claim may go in either in the Ho (null hypothesis) or Ha (H1, alternate hypothesis) depending on the key words in the statistical word problem. a. True b. False
What can be concluded by failing to reject the null hypothesis? A. either that the null hypothesis is correct or that the test procedure is not strong enough (i.e. that the sample size is not large enough) to reject the null hypothesis B. that the null hypothesis is correct, therefore the alternative hypothesis should be rejected C. that the function of the alternative hypothesis is incorrect D. that the alternative hypothesis is correct, therefore the null hypothesis should be rejected
Please explain it with proper reasoning. 3. The following statements are very important. Give them some careful thought and discuss them (a) When we fail to reject the null hypothesis, we do not claim that it is abso- lutely true. We simply claim that at the given level of significance, the data were not sufficient to reject the null hypothesis (b) When we accept the alternate hypothesis, we do not claim that the null hypothesis is absolutely false. We do...
True or false. If the p-value is 6%, then we reject the null hypothesis and accept the alternative hypothesis at a significance level of 10% but not at a significance level of 5%. True or false?
