Question

Could you solve the questions with R, please? (Only R please)

Use acf() function and auto.arima package in R to solve the questions 

I took a screenshot of the data. ( please write the codes based on the screenshot data) 
There are a total of 409 rows in the data.

When you write the R codes, could you also include explanations as well?  

 

Thank you
