Invalid atachment, so we can't see the problem. Also, wityhout seeing your thoughts, it is impossible to know if you are over-thinking. Please show us your work!Hi, I've been having trouble with the problem in the image below. I might be over-thinking it, but if anyone could help me with a) and b) it would be really appreciated.

a) is specified to be the "true" population distribution.I think I was over-thinking what this question was asking, and it might have been easier than I thought this whole time. But I might still be wrong. Here are my answers:
a) Population = right-skewed
Mean = 5.2
SD = 3
b)Sample data = (Here is the only part where I'm still confused. How do I know how the sample data is distributed from the information given?)
Mean = 4.6
SD = 3.2
c) Sampling distribution of mean = Normal (since the sample has more than 30 families)
Mean = 5.2 (I believe the mean of the sampling distribution of the mean is the same as the population mean).
Standard Error = .5 (I calculated this by diving the standard deviation of the population by the square root of 36)
