Answer

Explanation:

Step1: Identify lowest - bar

By observing the bar chart, the bar for television is the shortest. So television is repaired the least often. And its height is 3 on the number - of - repairs axis.

Step2: Subtract repair numbers

The number of repairs on DVD players is 8 and on televisions is 3. So (8 - 3=5).

Step3: Count devices below 9 repairs

The number of repairs for computer is 10, radio is 7, television is 3, DVD player is 8, and telephone is 9. Devices with fewer than 9 repairs are radio, television, and DVD player, so there are 3 types.

Answer:

(a) television, 3 (b) 5 (c) 3
