Answer 1

The ratio of false positives to false negatives is (d) 3.5

How to determine the ratio?

The table of values is given as

                          Activates.   Does not activate Row Totals

Lightning in area     88%           2%                           90%

No lightning in area 7%             3%                           10%

Column Totals           95%          5%                          100%

The false negative is when there is lighting and it does not activate

So, we have

False negative = 2%

The false positive is when  there is no lighting and it activates

So, we have

False positive = 7%

When represented as ratio, we have

Ratio = 7% : 2%

So, we have

Ratio = 7 : 2

This gives

Ratio = 7/2

Evaluate

Ratio = 3.5

Hence, the ratio is (d) 3.5
