**Educational Website Transcription:**---### Finding Z-Scores for the Normal CurveIn this tutorial, you will learn how to find the Z-score such that the area under the standard normal curve to the right is 0.45.1. **Start by accessing the appropriate table of areas under the normal curve.** Click on the icon to view a detailed table of areas under the normal curve. ![Table Screenshot](link-to-image-if-applicable.png) On this page, you will see a screenshot of a table that provides the cumulative areas corresponding to various Z-scores under the standard normal distribution.2. **Locate the approximate Z-score for the given area.** The problem requires the Z-score corresponding to a right-tail area of 0.45. To find this, you will need to: - Identify the desired cumulative area (1 - 0.45 = 0.55) since tables typically provide the area to the left of the Z-score. - Look up the cumulative area of 0.55 in the table.3. **Enter the Z-score.** Once you have located the correct value, round the Z-score to two decimal places and enter it in the provided space. **Input:** ``` The approximate Z-score that corresponds to a right tail area of 0.45 is __________. ```**Note**: If your table provides cumulative areas from the mean (0.5) or uses a different format, be sure to adjust your lookup process accordingly.**Example:**Using the table of areas, if we look for an area of 0.55, the corresponding Z-score is approximately 0.13. Hence,```The approximate Z-score that corresponds to a right tail area of 0.45 is 0.13.```---### Understanding the Table of Areas under the Normal CurveThe table displayed on the screen is crucial for finding Z-scores and understanding probabilities related to the normal distribution. Here is how to read it:- **Rows and Columns**: The rows and columns in the table represent the Z-scores. The value at the intersection of a specific row and column is the area (probability) to the left of that Z-score.- **Example of Usage**: To find the area to the left of Z = 0.13, locate the row for Z = 0.1 and the column for
