n a sample of 1313 randomly selected high school seniors, the mean score on a standardized test was 11901190 and the standard deviation was 165.6165.6. Further research suggests that the population mean score on this test for high school seniors is 10211021. Does the t-value for the original sample fall between minus−t 0.95t0.95 and t 0.95t0.95? Assume that the population of test scores for high school seniors is normally distributed.
