Q2. According to a survey on part-time workers (their monthly salaries can vary by different months), the average base salary for women is higher than the average base salary for men. The average base salary for women is $3000/month, andthe average base salary for men is $2750/month. Assume monthly salaries are normally distributed with a standard deviation of $300 for both men and women. Furthermore, assume salaries are independent across different months.
How much would a woman have tomake in a year to have a higher salary than 99% of her male counterparts?

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.
