For an aptitude test for quality-control technicians in an electronics firm, history shows scores to be normally distributed with a variance of 2500. For 20 applications who took the test, the sample standard deviation was 68. Is there enough evidence to reject the assumption that the variance of scores is 2500. Use significance level of 0.05.
