Answer:
a.The classification error rate for records that are truly fraudulent: By increasing the cutoff value, the non-fraudulent records will go down and this increases the error rate.
Also, if the cutoff value is down, the fraudulent records will increase and this lowers the error rate
.b.The classification error rate for records that are truly non-fraudulent: By moving up the cutoff value, the fraudulent records will go down and this decreases the error rate.
Also, if the cutoff value is down, the non-fraudulent records will go down and this increases the error rate.
It is given in the problem that in 1975, the number of restaurants chain is 15,250.
It is also given in the problem that 2000, the total number of restaurants is 21, 655. Therefore, the solution is is shown below:
% increase= ((# of restaurants is year 2000 - # of restaurants in year 1975)/number of restaurants in year 2000) * 100
% increase = (21,655-15250)/21,655 *100
% increase = 29.58%
