Please help URGENT! In a sample size of 12 randomly selected high school student seniors, the mean score on a standardized test was 1190 and the standardized deviation was 166. Further research suggests that the population mean score on this test for high school seniors is 1013. Does the t value for the original sample fall between -t0.90 and t0.90? Assume that the population for tests scores for high school students is normally distributed.

The t value of t = ??? And (does/does not) fall between -t.90 and t0.90 because t0.90= ???
