You are given a text file that contains the timetable for buses that travel a college campus. The first line of the file contains the name for each stop on the bus system separated by colons. Each following line contains the times using a 24-hour clock at which each bus in the system will arrive at a bus stop, also separated by colons.The timetable will have the following format:

Assume the age of death for all us burials(of persons over 5 years old) is approximately normally distributed and the sample mean is 68.84 and the standard deviation is 18.402926789.
Find the age at death such that 1.5% of US burials (of persons over 5 years old) were at least that old.
Find the probability that a burial randomly selected from all US burials (of persons over 5 years old) involved a person at least 30 years old.
Find the probability that a burial randomly selected from all US burials ( of persons over 5 years old) involved a person at most 85 years old.

A 195 g block is pressed against a spring of force constant 1.60 kN/m until the block compresses the spring 10.0 cm. The spring rests at the bottom of a ramp inclined at 60.0° to the horizontal. Using energy considerations, determine how far up the incline (in m) the block moves from its initial position before it stops under the following conditions.
(a)
if the ramp exerts no friction force on the block
m
(b)
if the coefficient of kinetic friction is 0.360
m
(c)
What If? If the ramp is 4.00 m long, what is the maximum coefficient of friction that would allow the block to reach the end of the ramp?
