Explain the notions of mathematical differences, managerially relevant differences, and statistical significance. Can results be statistically significant and yet lack managerial importance? Explain your answer. A retailer is interested in investigating whether doubling the value of manufacturer coupons will increase the number of shoppers. “Doubling” means that the store would give consumers a discount equal to twice the coupon face value, with the retailer absorbing the cost of the extra discount. Write the null and alternative hypotheses associated with this...

according to the simple linear regression result above.Interpret the results in terms suitable for the clinician, describing the statistical strength of evidence and possible clinical importance [Note, as a guide, that a difference of 5 in Methicillin DDDs would be of clinical importance.].Note: MRSA, in this case, is a binary variable and Methicillin is a continuous variable.Where I am confused is that since p=0.711 there is no doubt that the null hypothesis is accepted, but since both 5 and -5...

(1) What statistical test is appropriate?
  (1) What statistical test is appropriate? The tests to choose from are: One-sample t-test Independent t-test (unpaired t-test) Paired t-test F-test ANOVA Correlation Regression Chi-square test for association between factors (independent Chi-square) Chi-square goodness of fit (2) Why (explain your justification for using that test)? (3) As appropriate for the data and the test, label your dependent variables, independent variables and factors (if present). (This one only applies to some kinds of tests!)
