a.
To find the rangein head sizes for each hat size.
a.
Answer to Problem 35E
The complete table is obtained as:
Hat size | Small | Medium | Large | Extra | Large | |||
Head size (in.) | ||||||||
Range |
Explanation of Solution
Given information:
Consider, the table provided in the question,
Hat size | Small | Medium | Large | Extra | Large | |||
Head size (in.) |
Calculation:
To find the range in head size for each hat size, subtract the upper limit by lower limit of each hat sizes,
The range of head size of small sized hat:
The range of head size of medium sized hat:
The range of head size of large sized hat:
The range of head size of extra-large sized hat:
The complete table is obtained as:
Hat size | Small | Medium | Large | Extra | Large | |||
Head size (in.) | ||||||||
Range |
b.
To find the number of hats of each size purchased.
b.
Answer to Problem 35E
3 medium, 2 large and 1 extra-large sized hat should be purchased.
Explanation of Solution
Given information:
Head sizes are:
Calculation:
The table can be written as:
Hat size | Small | Medium | Large | Extra | Large | |||
Head size (in.) | ||||||||
Range |
Therefore,
Hence,
3 medium, 2 large and 1 extra-large sized hat should be purchased.
c.
To revise the table if the measurement of head is taken to the nearest
c.
Answer to Problem 35E
The revised table is obtained as:
