In a sample of 13 randomly selected high school seniors, the mean score on a standardized test was 1185 and the standard deviation was 160.7. Further research suggests that the population mean score on this test for high school seniors is 1016. Does the t-value for the original sample fall between - to 90 and to 90? Assume that the population of test scores for high school seniors is normally distributed. The t-value of t=3.64 does not fall between - to 90 and to 90 because to 90 =- (Round to two decimal places as needed.)
