Probability, mean and standard deviation for uniform distribution.
A group of students collected data at the Cedar Point amusement park and reported that the "wait time" to ride the "Top Thrill Dragster" roller coaster is consistently distributed within a range of 40 minutes to 90 minutes.
[a] find out the height and draw this uniform distribution.
[b] Show that the total area under the curve is 1.00.
[c] Determine the mean and standard deviation.
[d] What is the possibility that a particular student will wait between 50 and 60 minutes?
[e]what is the possibility a particular student will wait less than 60 minutes?
