61. Mozart Effect. Harvard University's Project Zero (http://pz.harvard.edu) found that listening to certain kinds of music, including Mozart, improved spatial-temporal reasoning abilities in children. Suppose that, in a sample of 100 randomly chosen fifth-graders, 65 performed better on a spatial-temporal achievement test after listening to a Mozart sonata. If appropriate, find a 95% confidence interval for the population proportion of all fifth-graders who performed better after listening to a Mozart sonata.
