Use Excel to find each probability. (Round your answers to 4 decimal places.) Probability a. P(80 < X < 110) for N(100,15) b. P(1.50 < X < 2.00) for N(0,1) c. P(4,500 < X < 7,000) for N(6000,1000) d. P(225 < X < 450) for N(600,100)

Step-by-step explanation:

a) P(80 < X < 110) for N(100,15)

P(80<x<110)0.656296243

b. P(1.50 < X < 2.00) for N(0,1)

zF (x)
