Question

Suppose a sample of 1762 floppy disk is drawn. Of these disks, 70 were defective. Using the data estimate the proportion of disks which are defective. Enter your answer as a fraction or decimal number rounded to three decimal places.

Answer 1

In order to find the proportion of disks that are defective, we can divide the number of defective disks by the total number of disks in the sample:

`p=(70)/(1762)=(35)/(881)`

Therefore the proportion is 35/881.
