Explanation Given: P ( − 1.48 < Z < 1.54 ) Approach: Take values from table 2 in appendix D. Calculation: Consider the given probability, P ( − 1.48 < Z < 1.54 ) Draw perpendicular from the x -coordinate equal to − 1.48 and 1.54 which is parallel to the y -axis on the standard normal curve. The shaded area enclosed these two perpendicular line is referred to the probability, P ( − 1.48 < Z < 1.54 ) To determine (b). The value of probability P ( − 1.48 < Z < 1.54 ) of the standard normal variable Z corresponding to the shaded area under the standard normal curve.

This means that when the Radius of Convergence of the Power Series is a "finite positive real number" r>0, then every point x of the Power Series on (-r, r) will absolutely converge (x ∈ (-r, r)). Moreover, every point x on the Power Series (-∞, -r)U(r, +∞) will diverge (|x| >r). Please explain it.
