Task 2: Generate 20,000 random numbers, each of which is a sum of X and Y. X follows a log-normal distribution with parameters -0.2 and -05; Y follows a normal distribution with -0.2 and -05. Once random numbers are generated, compute the mean and variance Repeat this process for 1000 times and record all results in an array. Save only top 10 rows and 5 rows to a text file You are required to complete this task using TWO approaches: (a) without for-loops and (b) with for-loops. Name those two files as "task2outputHW7_a.txt" and "task2outputHW7_b.txt", respectively. Add a screenshot (see below for a sample) to your notebook indicating that output text file is generated task2outputHW7 a - Notepad Eile Edit Format View Help 1.519 0.801 1.550 0.940 1.639 0.962 1.645 1.061 1.544 0.572 1.633 1.350 1.774 1.441 1.656 1.056 1.604 0.743 1.505 0.843 1.555 0.706 1.652 0.632 1.408 0.668 1.584 0.863 1.710 1.309 Extra credit (10%) (compare the computational efficiencies of two approaches.)
