Answer:

b. between 24 and 30 minutes

Explanation:

The standard deviation interval is 27±3, which translates to the interval between 24 and 30, as the limits are the result of the subtraction of one standard deviation (3) from the mean value (27). The standard deviation reflects the interval both in front and behind the mean. If we examined the interval within two standard deviations from the mean, it would be 21 to 33 minutes.
