A certain company prbduces vinyl for records in three grades (A, B, and C). Over
time, grade A vinyl has a 3% defective rate, grade B vinyl has a 5% defective rate,
and grade C vinyl has a 10% defective rate. Since grade A vinyl is less likely to be
defective, the company can charge more money than it can charge for the other two
grades. The company can also charge more money for grade B vinyl than grade C
vinyl.
Recently, the company found a batch of unlabeled vinyl in a warehouse. They could
determine the vinyl was from the same batch. The company randomly sampled 150
discs and found 8 defective discs.
(a) Construct and interpret a 90% confidence interval for the proportion of defective
discs in the batch.
(b) Does the interval calculated in part A clearly allow the company to determine the grade of vinyl?
