**Title: Probability Calculations Using Standard Normal Random Variables** **Objective:** Let \( Z \) be a standard normal random variable and calculate the following probabilities, drawing pictures wherever appropriate. (Round your answers to four decimal places.) **Problems:** (a) \( P(0 \leq Z \leq 2.41) \) - Input box for solution. (b) \( P(0 \leq Z \leq 2) \) - Input box for solution. (c) \( P(-2.10 \leq Z \leq 0) \) - Input box for solution. (d) \( P(-2.10 \leq Z \leq 2.10) \) - Input box for solution. (e) \( P(Z \leq 1.06) \) - Input box for solution. (f) \( P(-1.25 \leq Z) \) - Input box for solution. **Instructions:** To calculate each probability, you can use standard normal distribution tables (z-tables) or statistical software. For visual tasks, you may sketch the areas under the standard normal curve corresponding to each probability range. **Note:** Make sure you round your final answers to four decimal places. **Example Diagram Explanation:** For part (a), \( P(0 \leq Z \leq 2.41) \), you should shade the area under the curve from \( Z = 0 \) to \( Z = 2.41 \). The same procedure should be followed for other parts where you shade the areas under the curve corresponding to the specified ranges of \( Z \). **Interactive Tool:** Use the button labeled **"USE SALT"** to assist in calculations or visualizations where necessary. --- By following these guidelines and utilizing the provided tools, you will be able to accurately compute and visualize the required probabilities for a standard normal random variable.
