Answer:
0.4934
Explanation:
To obtain the area of the shaded region under then curve :
P(-2.48 < Z < 0) = P(Z < 0) - P(Z < - 2.48)
To obtain P( Z < x) = (x - μ) / s
Therefore :
P(Z < 0) - P(Z < - 2.48)
Using a Z probability calculator :
P(Z < 0) = 0.5
P(Z < - 2.48) = 0.0065691
Hence,
P(Z < 0) - P(Z < - 2.48) = 0.5 - 0.0065691
Therefore the shaded area under the normal probability curve is = 0.5 - 0.0065691 = 0.4934309
P(Z < 0) - P(Z < - 2.48) = 0.4934
