How do I set the problems below in R?


As per HomeworkLib policy we need to solve one question per post. Please post the remaining questions in another post.
How do I set the problems below in R? Use the rnorm function in R to generate 100 samples of X ~N(-1.0,2.5) (for help use ?rnorm ) and for each draw, simulate Yǐ from the simple linear regression model = 2.5+2.0x,+티, where e, N N(0,3 ). We were unable to transcribe this image
How do I set the problems below in R?

(ii) Split the sample into 2 subsets of size 25 and 75. For each subset, run the regression of Y on X. Add each fitted regression line (use color) to your plot from (i)....
How do I set the problem in R? My data file is leverage.csv and
the variables are: Date, SPX and VIX
Plot a summary of the predictive distribution (i.e., predictive mean and 90% interval. You will find lines command very helpful.) for VIX returns ranging from-20% to 20%.
I know how to do refraction problems involving different layers but I don't quite understand how to do it with prisms. Could you walk me through it? Thanks! 1.) The light beam in the figure below strikes surface 2 at the critical angle, ?c = 42
4. Set up (but do not solve) the associated v and w problems which homogenize the boundary conditions. Au=0 u(0, y)-f(u), 0 <y< b Vu(a,v) n-g(v), 0<y<b, Vu(r,0) n p(), 0<<a u(z,b)q(z), 0 <r<a. 0<r<a, 0<y < b I
PLEASE EXPLAIN HOW TO DO THESE PROBLEMS IN GREAT DETAIL SO THAT
I CAN DO SIMILAR PROBLEMS.
