In a sample of 15 randomly selected high school seniors, the mean score on a standardized test was 1187 and the standard deviation was 165.1. Further research suggests that the population mean score on this test for high school seniors is 1023. 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= does not fall between -to 90 and to go because t0.90 = ☐ (Round to two decimal places as needed.)
