An educator has developed a program to improve math scores on the Texas STAAR test. The average STAAR Mathematics test for third graders in the district was µ = 1472. A sample of n = 30 third graders took the new math training program before taking the STAAR Math test. The average score for the students was M = 1497 with a standard deviation of s = 145 (note, this is standard deviation, not variance). Was there a significant change in test scores? (Use a = 0.05, two-tail test) 20. Determine the degrees of freedom (df). 21. Determine the terit value. 22. Calculate the estimated standard error (SM) of scores for the sample.
