Unformatted text preview: in order to meet the regulation? Assume that the volume of serum in a vial is normally distributed. 3. Which of the following functions can represent a probability density functions for some random variable? For such functions, nd the correspond-ing cumulative distribution functions. a) f ( x ) = if x < if x > 1-1 if 0 < x < 1 b) f ( x ) = 0 if x < 0 if x > 1 1 if 0 < x < 1 c) f ( x ) = if x < if x > 10 / 11 1 . 1 if 0 < x < 10 / 11 d) f ( x ) = if x < if x > 1 1 . 1 if 0 < x < 1 e) f ( x ) = if x < 5exp(-5 x ) if x > 1 f) f ( x ) = if x < 5(exp(-5 x )-. 1) if x > g) f ( x ) = 1 2 exp(-x 2 ) 4. Find the value of C such that f ( x ) is a probability density function for some random variable. a) f ( x ) = if x < C exp(-x ) if x > b) f ( x ) = C exp(- | x | ) c) f ( x ) = if x < Cx if 0 < x < 3 if x > 3 2...
