The average salary for public school teachers for a specific year was reported to be greater than P39,385. A random sample of 30 public school teachers in a particular region had a mean of P41,680, and the population standard deviation is P5975. Is there sufficient evidence at the 0.05 level to conclude that the mean salary is greater than P39,385?
