infiormation, answer the following.

$($a$)$ What will be accuracy of the model $y^{{?}^{{?}^{?}}}=$ No

$($b$)$ Determine the classification accuracy.

$($c$)$ For the given confusion matrix, determine sensitivity and specificity.

$($d$)$ Which is more important class out of the two and why? Which measure has better ability

to capture the performance of the classifier: classification accuracy, sensitivity$,$

specificity. What can you say about the classifier?
