Let X
be a random variable with the standard normal distribution. Find: P (X < 1.13)
To find P(X < 1.13) when X follows a standard normal distribution with a mean of 0 and standard deviation of 1, we can use the standard normal distribution table or a calculator.
Using a standard normal distribution table, we find that P(X < 1.13) is approximately 0.8708.
Alternatively, using a calculator or statistical software, we can calculate this probability directly. Using the standard normal cumulative distribution function, we find:
P(X < 1.13) = 0.870761
Therefore, P(X < 1.13) is approximately 0.8708.
