you are completing a hypothesis test. You know the following items:
Decide whether to reject or fail to reject the null hypothesis.
Solution:
Given that,
Critical value = 8.547
Test statistic = 8.394
Test statistic < Critical value hence we fail to reject the null hypothesis
you are completing a hypothesis test. You know the following items: The test is a right-tailed...
You are completing a hypothesis test. You know the following items: The test is a two-tailed test. The critical value for the test is + 2.763 The standardized test statistic is -2.768 Assume the population is normally distributed. Decide whether to reject or fail to reject the null hypothesis.
1. What are null hypothesis and alternative hypothesis? 2. Inastatisticaltest,wehavethechoiceofatwo-tailedtest,aleft- tailed test, or a right-tailed test. Which hypothesis is the determining factor for choosing the direction of the test? (In other words, how would you decide it) 3. Forthesamesampledataandnullhypothesis,howdoesthe P-value for a two-tailed test compare to that for a one-tailed test? 4. Using P-value method, how would you reject or fail to reject the null hypothesis? (what is the decision criteria?) How does level of significance matter to the hypothesis...
