Answer 1

The range of calories in George's morning snack is about 80 less than the range of calories in his after noon snack.

Explanation:

We know that the range of calories in George's morning snack is:

170 calories

Since, the minimum number of calories in Morning snacks is: 90

Maximum number of calories in morning snacks are: 260.

Hence, Range is:Maximum-Minimum

Range= 260-90=170 calories.

Similarly for Afternoon snacks

The range of calories in George's afternoon snack is:

250 calories

Since, the minimum number of calories in afternoon snacks is: 225

Maximum number of calories in afternoon snacks are: 475.

Hence, Range is:Maximum-Minimum

Range= 475-225=250 calories.

Hence, the difference in the morning and afternoon range is:

250-170=80 calories.

Answer 2

Range is given by:
(maximum value)-(minimum value)
The range of calories from morning snack will be given as follows:
maximum value=225
minimum value=85
range=225-85=160

The range of calories from the evening snack will be:
maximum value=465
minimum value=225
range=450-225=240

The difference in range
240-160=80

Hence the conclusion will be:
The range of calories in George's morning snack is about 80 less
the range of calories in his after noon snack.
