On a nationally standardized reading comprehension test, the norm for the population mean was designed to yield a scaled score value of 50 for the population of fifth-grade students. A random sample of 10 elementary school children was tested, yielding scores of 48, 42, 55, 35, 50, 47, 45, 45, 39, and 42. Estimate whether this sample might be representative of the population for whom the test was designed. Test the hypothesis at the .05 level
