Math Problem Statement
Solution
To solve this problem, you are asked to find the probability for a standard normal distribution where:
Steps to solve:
-
Standard Normal Distribution: This refers to a normal distribution with a mean of 0 and a standard deviation of 1.
-
Find the z-value: The z-value here is 0.07. We need to calculate the probability that .
-
Use the z-table or a calculator: A z-table provides the probability that is less than a particular value. To get , we first find from the z-table, then subtract that value from 1.
-
Look up in the standard normal table. For , the value is approximately 0.5279.
-
Calculate :
So, the probability is approximately 0.4721 when rounded to 4 decimal places.
