A random sample of 30 students from UCSC are selected from a normal population with mu equal to 10 and sigma equal to 7. After a treatment is administered to the students, the researcher calculated the sample mean to be 13. Is there enough evidence to conclude that the treatment had an increasing effect at the 5% significance level? What hypothesis test is this?
