Answer #1

After executing a statement, there is no way you can modify the program flow because upon hitting enter, the code is placed in an area where, it cannot be edited. So there is no way you can change the program flow.

But, if there are errors, R notifies us about the error with the error message. Using this error message you can correct the error.

Example: Below is the snippet, where I wantedly made an error. As you can see the program didn't successfully compile. Using the error message, we can modify our code to be error free.

Editor: CodeMirror Layout: Vertical Language: R 1 ac(2, 3 4) 2 print(a) Run it (F8)Save it] Show input Absolute running time:

The correct code:

Editor: CodeMirrorLayout Vertical Language. R 1 a <- c(2, 3, 4) 2print (a) Run it (F8) Save it 1 Show input Absolute running

    When Ho: p = 0.25 is true and n = 10 only, the probability of cornmitting Type I error is about 0.08 which is substantially greater than the fixed α = 0.05. This is an issue for practical use of the hypothesis testing. By changing the null value 0.01 p 0.5 and the sample size 10Sn 1000, investigate the probability of committing Type I error. a. Complete the following table by the probability of committing Type I error. (First, write...
