QUESTION 7 Problem 2) True False (2) Type I Error is the probability that you fail to reject the null hypothesis when it was false. True False
QUESTION 1 A type Il error occurs if we fail to reject the null hypothesis when it is false. True False QUESTION 2
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
___is the probability of a Type II error; and ___ is the probability of correctly rejecting a false null hypothesis. 1-β; β β; 1-β α; β β; α A student hypothesized that girls in his class had the same blood pressure levels as boys. The probability value for his null hypothesis was 0.01. So he concluded that the blood pressures of the girls were the same as boys’. Which kind of mistake did he make? Type I error Type II...
QUESTION 21 A p value is the probability of obtaining the value of the test statistic or more extreme, if the null hypothesis is true. a. True b. False QUESTION 18 Type I error occurs when a. you reject a false null hypothesis b. you reject a true null hypothesis c. you fail to reject a false null hypothesis d. you fail to reject a true null hypothesis QUESTION 19 Type II error occurs when a. you reject a false...
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
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?
please show your work......................
The probability of a Type I error is denoted by C. a d, 1-α b. 1-B a. b. c. d. A Type I error is committed if we make a correct decision when the null hypothesis is false a correct decision when the null hypothesis is true an incorrect decision when the null hypothesis is false. an incorrect decision when the null hypothesis is true 6. a. b. c. d. A Type Il error is committed...
TRUE OR FALSE 1. A type 2 error occurs when we reject a true null hypothesis 2. All Chi- Square tests are right tailed tests. 3. It is valid to use the correlation coefficient to describe the relationship between major and working-status of a group of college students 4. If we decrease the Type 1 error rate, the Type 2 error rate will increase (given the same sample) 5. As the value of correlation coefficent (r) gets closer to -1,...
