For each probability and percentile problem, draw the picture.
A random number generator picks a number from 1 to 9 in a uniform manner.
1) Give the distribution of X.
2) Enter an exact number as an integer, fraction, or decimal.
f(x) = where <=x=>
3) Enter an exact number as an integer, fraction, or decimal.
5)P(3.25 < X < 7.5) =
6)P(X > 3.67) =
7)P(X > 6 | X > 3) =
8)Find the 80th percentile. (Round your answer to one decimal place.)
