In a sample of 13 randomly selected high school seniors, the mean score on a standardized test was 1198 and the standard deviation was 162.4. 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 - to 95 and to 95? Assume that the population of test scores for high school seniors is normally distributed. The t-value of t=N V fall between - to 95 and to 95 because to 95 =- (Round to two decima d.) does does not
