Suppose SAT Mathematics scores are normally distributed with a mean of 21 and a standard deviation of 5.3. A university plans to send letters of recognition to students whose scores are in the top 7%. What is the minimum score required for a letter of recognition?

Steps and excel commands are appreciated for notes

The final answer should be 4 decimal places with a sentence for context.

Thanks in advance.

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
