The sample data here is the cholesterol levels for 10 men diagnosed with high cholesterol. The first row represents levels from 10 men who did not use the drug and the second row from 10 different men who did use the drug. If we want to test the claim that the mean level for all men who use the drug is less than the mean for all men who do not use it, using the MS Excel output table below, what is the conclusion of the test at 5 % level of significance? No Drug 237 289 257 228 303 275 262 304 244 233 Drug 194 240 230 186 265 222 242 281 240 212

There is enough evidence that men who use the drug have less cholesterol levels than those men who do not use the drug.

There is not enough evidence that a significant difference exists between males who use the medicine and men who do not use the drug in terms of mean cholesterol levels.
