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 z=2.35z = 2.35, we follow these steps:

  1. Identify the cumulative probability for z=2.35z = 2.35 using standard normal distribution tables or a calculator.

    • The cumulative probability for z=2.35z = 2.35 is the probability that a value is less than or equal to 2.35 standard deviations above the mean.
  2. Look up the cumulative probability:

    • Using the standard normal distribution table, the cumulative probability for z=2.35z = 2.35 is approximately 0.9906.
  3. Calculate the area to the right of z=2.35z = 2.35: P(Z>2.35)=1P(Z2.35)P(Z > 2.35) = 1 - P(Z \leq 2.35) P(Z>2.35)=10.9906=0.0094P(Z > 2.35) = 1 - 0.9906 = 0.0094

Therefore, the area under the normal curve to the right of z=2.35z = 2.35 is approximately 0.00940.0094 or 0.94%.
