Specifications for the computer upgrades are 76 minutes and 81 minutes. Estimate the percentage of process output that can be expected to fall within the specifications. (Round your answer to 1 decimal place. Omit the "%" sign in your response.)

Explanation / Answer

Specifications for the computer upgrades are 76 minutes and 81 minutes.

Out of the 30 observations, only 6 values ( 84.3, 83.2, 83.9, 83.4, 82.8, 81.1) exceed the tolerances, or 20%.

24 values fall within the specifications.

Thus, it seems that the tolerances are being met: approximately 80% of the output will be acceptable.

Expected process output 80 %.
