Calories consumed by members of a track team the day before a race are normally distributed, with a mean of 1,600 calories and a standard deviation of 100 calories. If a normal curve is sketched using these data, what is the range for 3 standard deviations to the right and to the left of the mean?

Answer:

600 calories

Step-by-step explanation:

John has consumed 1600 calories out of which he has burned off 400. So the total calories for the day so far are:

1600-400

=1200 calories

He has to keep the count of calories upto 1800 per day and the consumed calories so far are 1200

So he needs to burn:

= 1800 - 1200

= 600 calories

He has to consume 600 calories more..

Hence 1000 is not a viable solution to the problem as the remaining count of calories that need to be consumed are 600 ..
