Explain how you chose the elements in operations. In the operation you chose to indicate, if you choose 1 or more elements, explain what the advantage of your choice is. 2. Make 10 observations to calculate T normal and T standard a. Calculate normal time assigning a Performance of 100% and T standard allowance of 15% b. Calculation of normal time assigning varied performance to each element and allowance of 12% 3. If a reliability of 95% were considered with a Variation of 5% of the standard time: a) What would be the sample size 4. Find an adequate size for both operations, considering the mean and deviation obtained by your study. Use a = 0.05 and a 3% standard time variation range in your results.
