Unformatted text preview: (c) Evaluate the cumulative distribution function (cdf) F X t ( x ). (d) Evaluate the probability density function (pdf) f X t ( x ). 3.-6. Please work the following problems from the text: 7.1, 7.2, 7.3, 7.6a 7. Based upon information provided in Chapters 4 and 6 of the text and the usage that X ∼ Z is read as “the random variable X is distributed according to the probability law Z ”, write out the probability mass functions (pmfs) or the pdfs and the associated mean or expected values EX for each of the following cases: X ∼ U ( a,b ) , X ∼ B ( n,p ) , X ∼ E ( α ) , X ∼ P ( λ ) , X ∼ L ( α ) , X ∼ N ( m,σ 2 ) . 1...
