Some statistics students estimated that the amount of changedaytime statistics students carry is exponentially distributed witha mean of $0.72. Suppose that we randomly pick 25 daytimestatistics students.
1. Give the distribution of X.
2. Give the distribution of
X.bar
(Round your standard deviation to three decimal places.)
3. Find the probability that an individual had between $0.68 and$1.00. (Round your answer to four decimal places.)
4. Find the probability that the average of the 25 students wasbetween $0.68 and $1.00. (Round your answer to four decimalplaces.)
