3. [7 points] You start with the following code and then complete the next lines: n <- 10 Print odd numbers from 10 to 24 using repeat loop. Hint. You can use modulo (%%) in Chapter 1.

6. [7 points] Please follow the following instructions. The instructions indicate how to download daily stock price of Amazon, Inc. from 2020-03-01 to 2020-04-30 from Yahoo! Finance. install.packages("quantmod") library(quantmod) getSymbols("AMZN", src = "yahoo", from='2020-03-01', to='2020-04-30') Then, with the following code, you can take the last column in AMZN, which is AMZN.Adjusted only, and assign the name AMZNAdj to the object.
