a is .05 and N-25, the probability of rejecting the null hypothesis if the mull hypothesis is true is: a. .os b..95 c. 05/25 - 01 d..95/25 = .19 e. insufficient information to answer as the popu 4. The sampling distribution of the mean always has the same distribution of the raw scores. a. mean b. standard deviation c. skew d. a and b e. all of the above S.

α is the probability of a Type I error, which occurs when we accept the alternative H1 when the null hypothesis Ho is true. True False A Type II error occurs when when a false null hypothesis is rejected. True False If a null hypothesis is rejected at the 5% significance level but not at the 1% significance level, then the p-value of the test is less than 1%. True False The power of a test is the probability of...
A Type II error occurs when when a false null hypothesis is rejected. true or false?
QUESTION 16 The power of the test, (1-B) provides the probability of correctly accepting the null hypothesis incorrectly accepting the null hypothesis correctly rejecting the alternative hypothesis correctly rejecting the null hypothesis In hypothesis testing if the null hypothesis is rejected, no conclusions can be drawn from the test the alternative hypothesis is true the data must have been accumulated incorrectly the sample size has been too small QUESTION 11 For a lower (left) tail test, the p-value is the...
When thinking about statistical hypothesis testing, power is A. the probability that the null hypothesis is true. B. the probability that the null hypothesis is false. C. the probability a false null hypothesis will be rejected. D. the probability a true null hypothesis will be rejected.
When is a null hypothesis accepted? What elements need to be in place for the null hypothesis to be rejected?
| A type I error occurs when: a true hypothesis is rejected a true hypothesis is not rejected a false hypothesis is rejected a false hypothesis is not rejected
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
If the null hypothesis is rejected when the null hypothesis is true, what type of error, if any, has been made? O O O O Correct decision Type Il error Type I error Type error Click to select your answer.
In hypothesis testing, if the null hypothesis has NOT been rejected when the alternative hypothesis is true, a. a Type II error has been committed b. a Type I error has been committed c. the correct decision has been made d. either a Type I or Type II error has been committed
