What is the advantage of a one-tailed test over a two-tailed test?@Answer found in section 4.3 The One-sample t-Test, in Statistics for Managers (Points: 1) Less data variability in the groups involved.Smaller critical values indicate significance.Rejecting at HO=.05 involves less chance of error.There are fewer calculations to make.;Question 3. 3. Which of the following is a provision of the central limit theorem? (Points: 1) A skewed distribution will remain skewed however it is plotted.There are limits to the range of scores that can be fitted to a distribution.A distribution based on sample means will be normal.There will always be theoretical differences between distributions.;Question 4. 4. Why do the critical values change with degrees of freedom for the t-tests?@Answer found in section 4.3 The One-sample t-Test, in Statistics for Managers(Points: 1) Different degrees of freedom define different t distributions.Because the critical values are calculated directly from degrees of freedom.The degrees of freedom reflect the value of SEM.The degrees of freedom are indexed to the M ??M difference.;Question 5. 5. The desired sample size depends only the size of the population to be tested. (Points: 1) True False;Question 6. 6. What is the alternate hypothesis in a problem where sales group two is predicted to be ?... significantly less productive than sales group one??@Answer found in sections 4.3 The One-sample t-Test and 4.4 Hypothesis Testing, in Statistics for Managers (Points: 1) HA:?1?? 2HA:? 1=? 2 HA:? 1>?2 HA:? 1
