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...
