whatever you do to the denominator is done to the numerator.
The accuracy in the research done by university is 0.81, sensitivity is 0.93, specificity is 0.81 and precision is 0.047.
Given sample size of 58205 and proportion of people donated 576. Cutoff is 0.5.
Probability is the chance of happening an event among all the events possible. It lies between 0 and 1.
TP=total people donated in sample, TN=total number of people,FP=donation,FN=No donation
Accuracy is calculated as under:
=(TP+TN)/(TP+TN+FP+FN)
=(268+23439)/(238+23439+5375+20)
=23707/29102
=0.81
Accuracy=0.81
Sensitivity is calculated as under:
=TP/(TP+FN)
=268/(268+20)
=268/288
=0.93
Precision is calculated as under:
=TP/(TP+FP)
=268/(268+5375)
=268/5643
=0.047
Their values are the probabilities in itself.
Hence accuracy is 0.81, sensitivity is 0.93, specificity is 0.81 and precision is 0.047.

Determine the amount used for frosting
To calculate this, we simply multiply 0.25 by the amount used for pumpkin bars
This gives:
<em>Hence, 0.375 cups of butter was used for frosting</em>
