To find the z score corresponding to an area of 0.93 under the standard normal curve, you can follow these steps:
- Look up the value of 0.93 in the standard normal distribution table (also known as the z table). This table provides the cumulative area from the left up to a certain z score.
- Find the closest value to 0.93 in the table. You may not find exactly 0.93, but look for the nearest value.
- Once you locate the closest value, trace back to the corresponding z score that is listed in the table.
For example, if you look up 0.93, you may find that it is closest to 0.9292, which corresponds to a z score of approximately 1.81. Thus, the z score such that the area to the left is 0.93 is approximately 1.81.
Another way to find the z score is to use statistical software or a calculator that includes functions for normal distribution calculations. Using these tools, you can input the cumulative probability of 0.93 to directly obtain the z score.
