A producer of gel pens claims that 96% of its pens can write more than 10,000 words without losing ink. A random sample of 500 pens is collected, and it is found that 470 of the pens can write more than 10,000 words without losing
ink. Let = the proportion of the sample of pens that can write more than 10,000 words.
The probability that 94% or fewer of these gel pens can write more than 10,000 words is 0.0115. Does this result
provide convincing evidence against the producer of the gel pens?
which is less than 50%
