Molly emailed her clients offering a free 30-minute massage for referrals. In the following validation set of 100, class 1 reflects the clients predicted to provide referrals and class 0 reflects the clients predicted to not provide referrals. Based on the confusion matrix, what was the False Negative (FN) of current clients who provided referrals for a free message?Actual Class Predicted Class 1 Predicted Class 0Class 1 18 11Class 0 11 60a. 29b. 18c. 11d. 60

Step-by-step explanation:

From the given data: the right table arrangement is:  

                         18                                    11

                          11                                   60

The True Positive is the number of current customers who were predicted to give references to a free back rub and who actually gave references to a free back rub.  

This number is given by the section in the segment relating to Predicted Class 1 and the line comparing to Atual Class 1 which is 18.

step-by-step explanation:

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
