THE SAMPLING DISTRIBUTION OF THE SAMPLE MEAN - Brief Chapter Test

[JinjaNinja1]

Hey guys,

I just took a test online 'The Sampling Distribution of the Sample Mean' chapter from Weiss 9th edition and I did not perform too well. Out of 8 questions I got only 3 fully correct, 4 partially correct and 1 completely wrong.

The ones I got wrong/partially wrong are these:

Question 1 - (9/10)


Question 3 - (0/5)


Question 4 - (3/4)


Question 5 - (1/7)


Question 6 - (2/6)

I'm having trouble with questions 3 and 5. Can somebody please explain to me the method to solve them? And I would also appreciate your remarks on questions 1,4, and 6 those of which I got partial credit for. I would like to know which parts in these questions I went wrong and how to correct them.

I tried on my own to see if there was something similar to Q3 and Q5 in the text book. But there was none.

Here's the dropbox link containing the screenshots of these questions. https://www.dropbox.com/sh/pco46wqjhcxivov/AACVux7MTE-1vy_5O2ofQk2wa?dl=0

Thanks so much for your help.

Erm... sorry, but these screenshots you posted to Dropbox don't actually contain the full problems. Like, problem #1 says:

The data in the table represents the wealth, in billions of dollars, of six people. Use the data to answer questions {a) through (e)

But then there's no table included. Similarly, problem #2 also references a non-existent table. I haven't checked the other six problems, but I assume they're all missing integral parts of the problem.
