A company wants to determine whether there is a significant difference in the salaries of its male and female employees. The company randomly selected a sample of 50 male employees and 50 female employees and recorded their salaries. The mean salary for the male employees was $70,000 with a standard deviation of $10,000, while the mean salary for the female employees was $75,000 with a standard deviation of $12,000. Conduct a hypothesis test with a 5% significance level to determine whether there is a significant difference in the salaries of the male and female employees.
