Complete Question:

If in a random sample of 400 items, 88 are defective, what is the sample proportion of defective items?

Answer:

22%

Explanation:

Given

x = 88

n = 400

Required

Determine the sample proportion, p

p is calculated using the following formula

p = (x)/(n)

Substitute values for x and n

p = (88)/(400)

p = 0.22

Convert to percentage

$p = 0.22 * 100\%$

$p = 22\%$

Hence, the proportion of defective items is 22%
