Question
**Problem Statement:** For a standard normal distribution, find: \[ P(z < -1.95) \] **Instruction:** To solve this problem, you will need to refer to a standard normal distribution table (Z-table) or use a statistical software/calculator that can compute probabilities for a standard normal distribution. The value you are looking for is the cumulative probability that a standard normal random variable is less than -1.95. This concept is crucial in statistics and is often used in hypothesis testing and confidence interval estimation. The standard normal distribution is a normal distribution with a mean of 0 and a standard deviation of 1. **Note:** - Ensure to understand how to navigate the Z-table or use the appropriate functions if using software. - This probability corresponds to the area under the standard normal curve to the left of z = -1.95.
