A random sample of 54 students from Cabrillo College are selected from a normal population with mu equal to 20 and sigma equal to 5. After a treatment is administered to the students, the researcher calculated the sample mean to be 21. Is there enough evidence to conclude that the treatment had an effect at the 5% significance level? What statistical test is this? One-Sample T-Test for Mean Chi-Square Test for Independence Two-Sample T-Test for Mean O One-Sample Z-Test for Mean
