Q6. (18pts). (Your solution should include R code and R output. R markdown should be used to present your solution) Exponential distribution is one continuous distribution with one parameter 1. The expected value and variance of exponential random variable are : H = 1/1, One population follows exponential distribution with parameter 1 = 10. Draw & random samples (sample size is n) from this population, calculate the sample means, and plot the histogram for the sample means. Hint: x
