A quality-conscious disk manufacturer wishes to know the fraction of disks his company makes which are defective. Step 1 of 2 : Suppose a sample of 707 floppy disks is drawn. Of these disks, 77 were 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:
Given,
n = 707
Out of these 77 were defective
x = 77
p^ = x/n
substitute values
= 77 / 707
= 0.1089
p^ = 0.109
