A Manufacturer Of Laptop Computers Claims That Only 1% Of Thier Computers Are Defective. In A Sample Of 600 Co? | All About Money Online

A manufacturer of laptop computers claims that only 1% of thier 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 in1000 of getting such o large proportion of defective laptops in the sample. Is there statistically significant evidence against the manufacturers claim? Why or why not?
