Formulate and test the appropriate Hypothesis

A psychologist believes that if classical music is played during a test, test scores will increase. In the past, the mean test score was 60. A random sample of 49 individuals wrote the test while classical music was in the background. The sample results showed a mean test score of 62 and a standard deviation of 6.3. Using a 5% level of significance, can the psychologist conclude that the mean test score has increased with classical music? Formulate and test the appropriate Hypothesis. Use the critical value approach.
