The data for fuel efficiency of a diesel engine in the lab test as follows: a. What is the range of the
true (or population) mean of each data set with 80% confidence interval? Which set of data is
acceptable if the maximum limit for 80% confidence interval is 57 ? b. Calculate the standard
normal distribution z and P(z) for data set 2 . Identify any outlier data for 80% confidence interval.
c. What is the maximum allowable standard deviation for data set 2 by Chouvenet 's criterion.
Identify any outlier data by this method.
