IN A ONE-TAIL HYPOTHESIS TEST WHERE YOU REJECT Ho ONLY IN THE UPPER TAIL, WHAT IS THE CRITICAL VALUE OF THE T-TEST STATISTIC WITH 10 DEGREES OF FREDOM AT THE 0.01 LEVEL OF SIGNIFICANCE?
Solution:-
Degrees of freedom =10
Significance level = 0.01 upper tail test
critical value t = 2.764

For a one-tailed hypothesis test where you reject Ho only in the lower tail, the critical value is-1.7247. What is the statistical decision if teTAT -2.69? What is the statistical decision? OA Since the teraT Value is greater than or equal to the critical value, reject Hn. OB. Since the tgTAT value is less than the critical value, reject Ho- O C. Since the teTAT value is greater than or equal to the critical value, do not reject Hg- OD....
Consider an upper tail test at the α =0.01 significance level with the test statistic =2.638 and degrees of freedom df=94 a) use the critical value approach to decide weather to reject ho b) consider the p-value approach to decide weather to reject ho
Match the rules for rejecting HO at the right to the following tests One-tail test with lower reject region 1. test statistic > positive critical value One-tail test with upper reject region 2. test statistic < negative critical value 3 Two-tail test with lower and upper reject regions 3. test statistic outside interval (negative critical value, positive critical value) 4. pvalue < a For any test hypothesis, ANOVA, or Chi Squared, this rule for rejecting HO always applies
A hypothesis test is conducted to test the null hypothesis that the mean is less than 12. Use a 0.01 level of significance. What type of test is this? Right tail Two tail Left tail What is the critical value? 2.33 -2.33 1.78 correct answer is not given Suppose the test statistic was -2.50 What is the conclusion? Fail to reject Ho. There is not sufficent evidence to support the claim that the mean is less than 12. Reject Ho....
Problem 6 (20 Points) One-Sample Hypothesis Nancy believes that the average running time of movies is equal to 140 minutes. A sample of 4 movies was taken and the following running times were obtained. 150 150 180 170 Answer the following: a. Assume you are trying to determine if the sample of movies taken differs from Nancy's assumption. Determine if the appropriate hypothesis test should be an upper tail, lower tail, or 2-tail test. b. Determine the value of the...
