Question

What’s the Error? An analysis showed that 0.06% of the T-shirts made by one company were defective. A student says this is 6 out of every 100. What is the student’s error?

Answer 1

According to the analysis,

Defective T-shirts made by one company = 0.06%

= 0.06/100

= 6/10000

But according to the student, defective T-shirts = 6 out of every 100 = 6/100

Hence, students error is that, the defective T-shirts are 6 out of every 1000 (not 100).
