Math Problem Statement
Find the area under the normal curve to the right of z=2.35
Solution
To find the area under the normal curve to the right of , we follow these steps:
-
Identify the cumulative probability for using standard normal distribution tables or a calculator.
- The cumulative probability for is the probability that a value is less than or equal to 2.35 standard deviations above the mean.
-
Look up the cumulative probability:
- Using the standard normal distribution table, the cumulative probability for is approximately 0.9906.
-
Calculate the area to the right of :
Therefore, the area under the normal curve to the right of is approximately or 0.94%.
