Normal distribution with a population mean

Scores on a national exam assume a normal distribution with a population mean of 50 and population standard deviation of 10 points. A sample of 36 exam scores was selected from UCA with a mean score of 58 points. Using a significance level of 0.01, determine whether scores on the exam have actually increased, statistically. What is the null hypothesis?
