## To calculate the percentage of males who don't satisfy the requirement of scoring at least 600 on the math SAT, you can use the provided computational tool. Here's how to do it:

1. Open the computational tool website provided: http://psych.colorado.edu/~mcclella/java/normal/accurateNormal.html

2. In the input boxes, enter the following values for the first problem:

- Mean: 531

- Standard Deviation: 114

- Start: 600 (the minimum score requirement)

- End: Choose a number at least 5 standard deviations above the mean, for example, 2000.

3. Click the "Submit" or "Calculate" button to get the result.

4. The tool will display the percentage of males who scored below the minimum requirement of 600. According to your calculation, the result is 27.25%.

Now, let's move on to the second problem. To calculate the percentage of babies born premature, you can follow these steps:

1. Open the same computational tool website: http://psych.colorado.edu/~mcclella/java/normal/accurateNormal.html

2. Input the following values for the second problem:

- Mean: 268 (mean duration of pregnancies)

- Standard Deviation: 15 (standard deviation of pregnancy duration)

- Start: Choose a number around 180 or less (to represent premature births)

- End: 247 (3 weeks early from the mean duration)

3. Click the "Submit" or "Calculate" button to obtain the result.

4. The tool will provide you with the percentage of babies born premature. According to your calculation, the result is 8.08%.

Keep in mind that while a normal distribution is generally used for statistical calculations, there may be exceptions, such as pregnancies with a high risk of short-term miscarriages.
