ufineturet of sunflower oil uses machines to distribute liquid ingredients into bottles that move along a filling time. The machine the distributes is working properly when 8 ikinces are distributed Suppose that the average amount distributed in a particular sample of 30 bottles is 8.91 ounces. Assume that the wariance of the process is known to be 0.03 ounces squared. Is there evidence that the ruchire should be stoppet (when not ounces are distributed), and production wait for repairs" The lost production from a shutdown is potentially a great that management feels that the level of confidence in the analysis should be 99%

Confidence Intervals

When we calculate intervals in probability and statistics, it can be simply termed as finding out a confidence interval. The confidence interval is usually calculated from the data set which is observed. The value of the parameter that needs to be calculated is present here only.
