Zenich Corp manufactures laptops. The waiting time is 72 minutes before the start of production and the manufacturing lead time
1 answer:
Answer:
The Manufacturing cycle efficiency = 69 %
Step-by-step explanation:
The waiting time is = 72 minute
The manufacturing lead time is ( )= 160 minutes
Total cycle time ( ) = 160 + 72 = 232 minutes
Manufacturing cycle efficiency =
⇒ Manufacturing cycle efficiency =
⇒ Manufacturing cycle efficiency = 69 %
Therefore, the Manufacturing cycle efficiency = 69 %

Answer:
The 95% confidence interval obtained with a sample size of 64 will give greater precision.
Step-by-step explanation:
We are given the following in the question:
A 95% confidence interval is calculated with the following sample sizes
The population mean and standard deviation are unknown.
Effect of sample size on confidence interval:
- As the sample size increases the margin of error decreases.
- As the margin of error decreases the width of the confidence level decreases.
- Thus, with increased sample size the width of confidence level decreases.
If we want a confidence interval with greater precision that is smaller width, we have to choose the higher sample size.
Thus, the 95% confidence interval obtained with a sample size of 64 will give greater precision.
