Assume that six samples of pesticide concentrations in Ohio plants are gathered, yielding a sample standard deviation of 4.3 ppm and a sample mean of 28.2 ppm Let's pretend that the The observations are regularly distributed (at least roughly). a) For the mean pesticide concentration, construct a 50% confidence interval. b) With a 50% certainty, you can say that the genuine mean pesticide concentration is lower. What is the amount? c) Assume that the true standard deviation is 4.3 parts per million (ppm). If You want to be 99 percent certain that the projected mean pesticide concentration is within 2 percent of the actual concentration. How many samples should you take if the true mean is ppm?

The observations are regularly distributed (at least roughly).
a) For the mean pesticide concentration, construct a 50% confidence interval.
b) With a 50% certainty, you can say that the genuine mean pesticide concentration is lower.
What is the amount?
c) Assume that the true standard deviation is 4.3 parts per million (ppm). If
You want to be 99 percent certain that the projected mean pesticide concentration is within 2 percent of the actual concentration.
How many samples should you take if the true mean is ppm?
