A researcher hypothesizes that individuals who listen to classical music will score differently than the general population on a test of spatial ability. On standardized tests of spatial ability, the population mean is 58. A random sample of 14 individuals who listen to classical music is given the same test. Their scores are 50, 57, 61, 65, 56, 53, 63, 67, 55, 60, 54, 64, 62, 60.
a. Is this a one- or two-tailed test?
b. What are the null and alternative hypotheses for this study?
c. Compute t obtained.
d. What is t critical value?
e. Should the null hypothesis be rejected? What should the researcher conclude?
