Some statistics students estimated that the amount of change daytime statistics students carry is exponentially distributed with a mean of $0.88. Suppose that we randomly pick 25 daytime statistics students.
Give the distribution of X. (Round your standard deviation to three decimal places.)
X ~ N (0.88 , 0.88/√25)
A) Find the probability that an individual had between $0.74 and $0.95. (Round your answer to four decimal places.)
B)Find the probability that the average of the 25 students was between $0.74 and $0.95.
