$1.$ First, sort on predicted probability column, Column D $($descending$)$

$2.$ Calculate n$11,$ n$00,$ n$10,$ n$01.$ for all cutoff Probabilities provided in Column F$.$ I provided these

numbers $($n$11,$ n$00,$ n$10,$ n$01)$ for cutoff of $1,0\mathrm{.}6$ and $0\mathrm{.}5.$

$3.$ Calculate the FPR and FNR for the cutoff probabilities $($See the formulas on $$Notations and Error

Rates$$ in the Reference Materials section$).$

$4.$ Plot FNR and FPR vs$.$ Cutoff probabilities $($X axis is Cutoff Probability, column F$).$ Label the axes.

Note: Your charts should somewhat be similar to Figure $9\mathrm{.}1$ on page $468$ of textbook.

$5.$ Construct the confusion Matrix for cutoff $=0\mathrm{.}5.$
