What distinguishes a z-test from a one-sample t-test?A researcher conducted a study looking at the effect of music education on IQ and got a sample of 40 people to participate in a music education class. The average of the sample’s IQ after participating in the class was 105. We know that the average IQ of the population is 100 with a standard deviation of 15. Which statistical test would be the most appropriate for this study? Why did you come...
