1. In a test to compare the effectiveness of two drugs designed to lower cholesterol levels, 75 randomly selected patients were given drug A and 100 randomly selected patients were given drug B. Those given drug A reduced their cholesterol levels by an average of 41 with a standard deviation of 12, and those given drug B reduced their levels by an average of 42 with a standard deviation of 16. The units are milligrams of cholesterol per deciliter of blood serum. Can you conclude that the mean reduction using drug B is greater than that of drug A? Find the P-value and state a conclusion. Round the answer to four decimal places.

The P-value is _
