An educator has developed a program to improve math scores on on the Texas STAAR test. The average STAAR mathematics test for third graders in the district was a mean of 1472. A sample of n=30 third graders took the 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. Calculate the estimated standard error of scores for the sample.
