question 153

Essay

A manufacturer of laptop computers claims that only 1% of their computers are defective. In a sample of 600
computers, it was found that 3% were defective. If the proportion of defectives were really only 1%, there would
be less than 1 chance in 1000 of getting such a large proportion of defective laptops in the sample. Is there
statistically significant evidence against the manufacturer's claim? Why or why not?
