LuckyWell [14K]

Answer:

The correct answer is "(18, 30) minutes".

Step-by-step explanation:

Mean,

= 24

Standard deviation,

= 2

The range of minutes where 99.7% of individuals completed the quiz will be:

= Mean \pm 3\times Stdev

On substituting the values, we get

= 24 \pm 3\times 2

= 24 \pm 6

now,

= 24-6

= 18

Or,

= 24+6

= 30

i.e., 18 to 30 minutes
