Does the amount of hazardous material absorbed by the bodies of hazardous waste workers depend on gender? The level of lead in the blood was determined for a sample of men and a sample of women who dispose of hazardous waste as a full time job. You want to test the hypotheses that the amount absorbed by men is greater than the amount absorbed by women. After performing a hypothesis test for two independent samples, you see a p-value of 0.3307. Of the following, which is the appropriate conclusion?

 

1) We did not find enough evidence to say the average amount of lead absorbed by men is greater than the average amount of lead absorbed by women.

2) The average amount of lead absorbed by men is significantly greater than the average amount of lead absorbed by women.

3) We did not find enough evidence to say a significant difference exists between the average amount of lead absorbed by men and the average amount of lead absorbed by women.

4) The average amount of lead absorbed by men is less than or equal to the average amount of lead absorbed by women.

5) We did not find enough evidence to say the average amount of lead absorbed by men is less than the average amount of lead absorbed by women.
