LuckyWell [14K]

Answer:

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

Step-by-step explanation:

= 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
