WebbFirst, I convert P ( X < b) to be using the standard normal distribution. This gives P ( Z < b − μ σ) = 0.05 or P ( Z < b + 1 2) = 0.05. By looking into a table with all values for ϕ ( z), I found out that b + 1 2 = − 3.29 or b = − 7.58. The solution that was given by the teacher is − 4.29. I don't know what I did wrong? statistics WebbV a r ( X) = σ 2. Var (X) = \sigma^2 V ar(X) = σ2, respectively. In R there exist the dnorm, pnorm and qnorm functions, which allows calculating the normal density, distribution …
