A molding machine in a factory was not working very well. About a third of the time, the plastic squirt guns that it was making come out with a flaw in the handle. The repair mechanic adjusted the stamping pressure. Then she ran one gun through. It came out just fine, so she figured she had solved the problem. What was/were the error(s) in the conclusion of the repair mechanic? a. Not enough subjects
b. Subjects were not similar
c. Conditions were not kept the same
d. The experiment was not reproduced

a. Not enough subjects

Explanation:

In the context, it is given that in a factory, a molding machine is not working properly. The molding machine produces a gun made of plastic. But the machine was produces a defective piece about a third of he time it produces the gun.

The mechanic adjusted and repaired the stamping pressure and ran only one gun through which came out to be fine. But there was an error in the conclusion of the repair mechanic as she did run the machine only one time. She did not have enough subjects and should have run many times to see if the error still exists, as the machine showed error only about a third of the time during the process.

Thus the error in the experiment includes the lack of the enough of the subjects. We cannot come to the conclusion only with one time success.

i think that c)gold was found there

but i am not sure

events in order:

1.       vishnu schist

2. zoroaster granite

3. bass limestone

4. hakatar   shale

5. igneous intrusion

6. shinumo quartzite

7. dox sandstone

8. tapeats limestone

9. bright angel shale

10. muav limestone

11. temple butte limestone

12. redwall limestone  

nonconformity

answer: the unkar group shows angular unconformity because the layers are turned at angle.

unconformity

answer: specifically the angular unconformity occurs between the cambrian and precambrian rocks. the dox sandstone, shinumo quartzite, hakatar shale, and bass limestone have been filled. an angular unconformity occurs between the cambrian and precambrian rocks. the dox sandstone, shinumo quartzite, hakatar shale, and bass limestone have been filled.

disconformity

answer: the disconformities aremarked irregular lines between the sedimentaryrocks layers.
