On your R code … please make sure you upload the code itself, not the console output. The code should run and, without any modifications, print out all the computation results, figures, etc. One way to check that it does that is to click “Session”, then “Terminate R” (that will clear your workspace). Once RStudio has restarted, open your code file and press “Source.” That will run all the code in that file. Look at the console output. Are there any errors? Did all your computations print? Did your figures show?

Just spotted a typo in #4 of assignment 1. The numbers should be 0.45 and 0.55 rather than 45 and 55. Corrected version attached.
Also, “use the central limit theorem” means to use the normal distribution as the approximate distribution of Y-bar.

If you can’t do it, plz let me know as quickly as possible, I just ordered 2 pages, if it is not enough, plz call me as soon as you can, because I’m not read email very often. Thx.
