If the following R data link doesn't work, use:

hw2_data = read.csv("https://raw.githubusercontent.com/gweon/stat420/master/hw2_data.csv")

This is r-studio problem.

2. For question 2, you will use an imported data. Run the following R code (in blue) and use the hw2 data dataset to answer the questions (a)-(d). R code: hw2.data read.csv("https://raw.githubusercontent.com/gweon/stat420/master/hw2.data.csv") The imported dataset contains 25 observations with 2 variables: y (response) and x (predictor). Please include your R codes and outputs for all the following questions. (a) Consider the SLR model Y-Ao +Aztei where i-1, , 25. obtain A, A, and R2. (1 pt) (b) At x=6, construct a 90% prediction interval for a new observation. (1 pt) (c) Is there a significant linear relationship between y and z? Answer the question by testing H0 : 1-0 vs H1 : 10 at = 0.05. (1 pt) (d) Test H0 : A = 10 vs H1: A
