Left of z = 0.49 and right of z = 2.05, the area underneath the standard normal curve is equal to 0.7081.
<h3>What is the standard normal curve?</h3>
The horizontal axis is approached by the standard normal bend as it extends indefinitely both in directions without ever being touched by it. The center of the bell-shaped, z=0 standard normal curve. Between z=3 and z=3, almost the entire area underneath the standard normal curve is located.
<h3>Use of the
standard normal curve:</h3>
Use the normal distribution's standard form to calculate probability. Since the standard normal distribution is indeed a probability distribution, the probability that a variable will take on a range of values is indicated by area of the curve between two points. 100% or 1 is the total area beneath the curve.
<h3>According to the given data:</h3>
the region to the left of the standard normal curve,
z=0.49
To the right of,
z = 2.05
So,
The area will be:
= P[z < 0.49] + P[ z >2.05]
= P[z < 0.49] + 1 - P[ z < 2.05]
= .6879 + 1 - .9798
= 0.7081
Left of z = 0.49 and right of z = 2.05, the area underneath the standard normal curve is equal to 0.7081.
