1. In late 2007, it was reported that 79% of U.S. adults owned a cell phone (data extracted from E.C. Baig, "Tips Help Navigate Tech-Buying Maze", USA Today, November 28, 200, p.5B). Suppose that by the end of 2009, that percentage was 85%. If a sample of 10 U.S. adults is selected, what is the probability that:
(a) P(X = 8)
(b) P(X ≥ 8)
(c) P(X ≤ 10)
(d) Provide a substantive answer to the question.
2. Mean of 2.0 seconds and Standard Deviation of 0.5
(a) P(X < 2)
(b) P(1.5 < X < 2.5)
(c) P(X > 1.8)
(d) P(A < X) = 0.99. What is A?
3. Read Managing Ashland MultiCommService on page 273
Mean of 1.005 and Standard Deviation of 0.10
(a) P(
< 1.0) =
