Given the normal curve:

Between z = -3.05 and z = 3.05

Let's find the indicated area under the standard curve.

To find the area, we have:

P(-3.05 < z < 3.05) = P(z < 3.05) - P(z < -3.05)

Using the standard normal diatribution table, we have:

NORMSDIST(3.05) = 0.9989

NORMSDIST(-3.05) = 0.0011

Thus, we have:

P(z < 3.05) - P(z < -3.05) = 0.9989 - 0.0011 = 0.9978

Therefore, the indicated area under the standard normal curve is 0.9978

ANSWER:

0.9978
