In a sample of 15 randomly selected high school seniors, the mean score on a standardized test was 1180 and the standard deviation was 164.3. Further research suggests that the population mean score on this test for high school seniors is 1020. 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 oft= V fall between - to.90 and to.90 because to.90 =| (Round to two decimal places as needed.)
