Chapter SH, Problem 5.19EP

a.

To determine

To find range of CD price.

Answer to Problem 5.19EP

Range of CD price is 3.

Explanation of Solution

Given information:

  

If price ranged $1.5 above and below the average CD price

Calculation:

The CD's average price=15.50

Above 1.5 the average CD price=15.5+1.5=17

Below 1.5 the average CD price=15.5-1.5=14

Range=17-14=3

Hence, range of CD price is 3.

b.

To determine

To find range of book price.

Answer to Problem 5.19EP

Range of book price is 4.50.

Explanation of Solution

Given information:

  

If price ranged $2.5 above and below the average book price

Below 2.25 the average book price=19-2.25=16.75

Range=21.25-16.75=4.50

Hence, range of book price is 4.50.
