Draw and label the graphs of the pdf, Mathematics

1. What is the value of Φ(0)?

2. Φ is the pdf for N(0, 1); calculate the value of Φ(1.5).

3.  Suppose X ~ N(0, 1). Which, if either, is more likely: .3 ≤ X ≤ .4, or .7 ≤ X ≤ .8? Explain your answer (you do not need to calculate these values).

4. Draw and label the graphs of the pdf (together, on one set of axes) of N(0,1) and N(-1, 2). Your graphs should display how the different parameters of the two distributions affect the pdfs.
