Question

You are testing a scale system that determines shipping rates for a regional web-based auto parts distributor. You want to group your test conditions to minimize the testing.Identify how many equivalence classes are necessary for the following range. Weights are rounded to the nearest pound.

Weight (in lbs.) 1 to 10 | 11 to 25 | 26 to 50 | 51+
Shipping Cost $5.00 | $7.50 | $12.00 | $17.00
A. 4
B. 5
C. 6
D. 8

Answer 1

To determine the number of equivalence classes necessary for the given range of weights, we need to consider the boundaries of each range and identify the distinct characteristics within each range.

Step-by-step explanation:

To determine the number of equivalence classes necessary for the given range, we need to consider the boundaries of each range and identify the distinct characteristics within each range. In this case, we have four ranges: 1 to 10 lbs, 11 to 25 lbs, 26 to 50 lbs, and 51+ lbs. The equivalence classes can be defined as follows:

1. 1 to 10 lbs: This range has one equivalence class as it represents weights from 1 to 10 lbs.
2. 11 to 25 lbs: This range has one equivalence class as it represents weights from 11 to 25 lbs.
3. 26 to 50 lbs: This range has one equivalence class as it represents weights from 26 to 50 lbs.
4. 51+ lbs: This range has one equivalence class as it represents weights greater than 50 lbs.

Therefore, a total of 4 equivalence classes are necessary for the given range.
