Question

Suppose a sample of 401floppy disks is drawn. Of these disks, 36were defective. Using the data, estimate the proportion of disks which are defective. Enter your answer as a fraction or a decimal number rounded to three decimal places.

Answer 1

To estimate the proportion of defective floppy disks, divide the number of defective disks by the total number of disks.

Step-by-step explanation:

To estimate the proportion of defective floppy disks, we can use the formula:

Proportion of defective disks = Number of defective disks / Total number of disks

Plugging in the given values:

Proportion of defective disks = 36 / 401 ≈ 0.0898

Therefore, the estimated proportion of defective floppy disks is approximately 0.0898.
