In a chemical process, the amount of a certain type of impurity in the output is difficult to control and is thus a randomvariable. speculation is that the population mean amount of the impurity is 0.20 gram per gram of output. it is known thatthe standard deviation is 0.1 gram per gram. an experiment is conducted to gain more insight regarding the speculationthat u = 0.2 the process is run on a lab scale 50 times and the sample average 3% turns out to be 0.23 gram per gram. comment on the speculation that the mean amount of impurity is 020 gram per gram. make use of the central limittheorem in your work.
