SOLUTION:-
yes,If we reject a null hypothesis, should we state that the alternative hypothesis to be true.
Because,
If we have to test the hypothesis means we have to prove the that reject the null hypothesis or fail to reject the null hypothesis.
In case if we reject the null hypothesis then we should accept the alternative hypothesis.
In case if we fail to reject the null hypothesis then we should reject the alternative hypothesis.
There are two hypothesis in hypothesis testing null hypothesis(H0) and alternative hypothesis(Ha).
If we reject a null hypothesis, should we state that we have proved the alternative hypothesis...
1. When we reject the null hypothesis, we are saying that… we have proven the alternative hypothesis to be true we have proven the null hypothesis to be false our sample is too unlikely to have been produced by the null distribution our sample had a mean approximately the same as the population our sample had a standard deviation smaller than the population
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
All things being equal, when we have a two-tailed Alternative Hypothesis test it is easier to reject the Null Hypothesis (when compared to a one-tailed test). True False
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.
8. A very small p-value indicates that: a. we should accept the alternative hypothesis. b. we should reject the null hypothesis and the alternative hypothesis. c. we should reject the null hypothesis. d. we should not reject the null hypothesis.
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?
I. IF we do not reject the null hypothesis when the alternative hnthsinthen we have made Type B error (b) Correct decision (e) Type I error (a) Type I1 error Use for Problems 2 and 3. The data below shows the top 10 teams' winning percentages (z) and powe ratings (u) for the 2013-2014 NCAA basketball season, according to vww.teasrankings.com bo 100.47 b 20.43 08330.694 2. Interpret the estimated slope of the line. (a) For a 1-game decrease in power...
please help with t test snd hypothesesis If we reject a null hypothesis at the 1% significance level, then we have hypothesis is false. evidence that the null For this problem create your own t-test and state your null hypothesis, alternative hypothesis Draw out the normal distribution curve and the critical region. You can assume a two tail test. Label the critical region. strong weak non existent
STEP 2 State the Null and Alternative (Research) hypotheses NULL Hypothesis ALTERNATIVE Hypothesis Is this a one or two tailed test (if a one tailed test, what direction)? STEP 3 Define the elements of the problem What is the population or populations of interest? What is the sample? 3. The President claims that 100,000 jobs were created last month. You don't believe this claim is true, so you examine a sample of 1,000 records from the Bureau of Labor Statistics...
State whether the standardized test statistic t indicates that you should reject the null hypothesis. Explain. (a) t = 2.203 (b) t = 0 (c) t = 2.113 (d) t = - 2.203 1 ro -4 to = 2.158 (a) For t = 2.203, should you reject or fail to reject the null hypothesis? A. Fail to reject Ho, because t> 2.158. B. Reject Ho, because t> 2.158. C. Fail to reject Ho, because t< 2.158. D. Reject Ho, because...
