Use Excel to generate a column of x values from 0 to 2.5 in steps of 0.05 (that means your column must have numbers like 0, 0.05, 0.1, 0.15, . . . , 2.5).

Plot the PDF f(x) on your computer screen for the different values of x mentioned above for the following distributions.

(a) Uniform (use A = 0 and B = 2.5)

(b) Exponential (use mean = 2)

(c) Gamma (use parameters 1.7 and 1.2)

(d) Normal (use µ = 1.25 and σ = 0.4)

Please attach the PDF curves you plot. Under each plot, write down the name of the distribution

Solutions

Expert Solution

Here first column is points from 0 to 2.5 at steps 0.05.

2nd,3rd,4th,5th column represents probability of x under distribution of (a),(b),(c),(d).

For uniform =1/(2.5-0) then drag down

For exponential =EXP(-A2*0.5)/2 then drag down A2 is firs value of X.

For gamma =GAMMA.DIST(A2,1.7,1.2,FALSE) here cdf is false .

For normal =NORM.DIST(A2,1.25,0.4,FALSE)

Use the Rejection Method to generate n = 1000 values for a random variable X distributed as Exponential (lambda=5). Create a density histogram for your generated values and superimpose the probability density function of the target distribution to the histogram. Use the generated values to estimate the mean, standard deviation, and the probability that X < 2. Compare them with the theoretic values which are 0.2, 0.2, and 0.97725, respectively. Report the rejection rate. Write in R code
