Question

Question 3 A recycling plant wants to estimate the average time needed for a new machine to process a plastic bottle. A sample of 35 bottles required an average processing time of 3,4 minutes for each bottle. Assuming that the population standard deviation is 0,9 minutes, construct a 95% confidence interval estimate, to one decimal place, for the average time to process a plastic bottle.

          Question 3
A recycling plant wants to estimate the average time needed for a new machine to process a plastic
bottle. A sample of 35 bottles required an average processing time of 3,4 minutes for each bottle.
Assuming that the population standard deviation is 0,9 minutes, construct a 95% confidence interval
estimate, to one decimal place, for the average time to process a plastic bottle.

Step 1

- Sample mean (x̄) = 3.4 minutes - Sample size (n) = 35 bottles - Population standard deviation (σ) = 0.9 minutes - Confidence level = 95% Show more…
