A Six Sigma team is testing pilot test results to see if they have made a ststistically significant improvement.They need to test this hypothesis statistically and determine the 95% Confidence Interval for the improvement.Data from the baseline and pilot test are reported in the table below:

	Defects	Good	Sample	Defect rate
Baseline	6290	613710	620000	0.01015
PILOT TEST	466	48534	49000	0.00951

B1. State the hypothesis.

B2. Test the hypothesis and state the results in statistical and business statements.

B3. State the 95% confidence interval for the baseline process defect rate in %.
