Many people who bought z-game gaming systems over the holidays have complained that the systems they purchased were defective. in a sample of 1200 units sold, 18 units were defective. determine the upper limit for the 95% confidence interval for the population proportion. round your answer to three decimals.

The upper limit for the 95% confidence interval for the population proportion of defective gaming systems is 0.022

Step-by-step explanation:

Upper Limit for 95% Confidence Interval can be calculated using p+ME where

and margin of error (ME) around the mean can be found using the formula

ME= where

Using the numbers we get:

ME= ≈ 0.007

Then upper limit for the population proportion is 0.015+0.007 =0.022

relating to or denoting a system of numbers and arithmetic based on the number ten, tenth parts, and powers of ten.
