Given a normal distribution with μ = 50 and o= 10, find: (a) the area under the curve to the left of x = 34.5; (b) the area under the curve to the right of x = 42.7; = 45.4 and x = 58.6; (c) the area under the curve between x (d) the value of x that has 91% of the curve to its left; (e) Find c, such that P(|X - µ| < c) = 0.8.
