Question 3: In this exercise you will use R to compute the normal density and the cumulative distribution functions using dnorm and pnorm. (a) For any given values of μ, σ, and y, what value does dnorm(y, μ,o) compute? Write the expression in terms of μ, and y. How does the value compare to the value computed by 1/0+dnorm((y-μ)/o)? Explain. (b) For any given values of μ, σ, and y, what value does pnorm(y,μ, o) compute? Write the expression in terms of μ, and y.How does the value compare to the value computed by pnorm((y-μ)/o)? Explain.
