10. Which of the following parameter configurations would make it appropriate to approximatetheBin(n, p) distribution with a normal distribution? (a)n= 10,p= 0.7(b)n= 20,p= 0.8(c)n= 30,p= 0.4(d)n= 40,p= 0.1(e) none of the above Exhibit II.Suppose a continuous random variableXhas the following probability densityfunction (pdf):f(x) =(kx20x20otherwise11. Refer to Exhibit II. What is the value ofk? (Recall that the total area under the pdf mustbe 1.) 12. Refer to Exhibit II. What is the probability thatX1? Exhibit III.The checkout durationX(hours) for a book on a 2-hour reserve at a collegelibrary has the following cumulative distribution function (cdf):F(x) =0x <0x2/40x <212x13. Refer to Exhibit III. What is the median checkout duration? 14. Refer to Exhibit III. What is the probability that X 1? 3
