In one area, monthly incomes of technology related workers have a standard deviation of $650. It is believed that the standard deviation of monthly incomes of non- technology workers is higher. A sample of 71 non-technology workers are randomly selected and found to have a standard deviation of $750. Test the claim that non- technology workers have a higher standard deviation. Use a = 0.05. Test Statistic Round to %3D thousandths place. P-Value = Round to thousandths place. Decision = (Write %3D 'Reject' or 'Fail to Reject')
