Answer 1

Frequency distribution and Frequency Histogram:

Bins	Labels	Frequency	Cumulative %
1500	300-1500	4	19.05%
2700	1500-2700	10	66.67%
3900	2700-3900	1	71.43%
5100	3900-5100	4	90.48%
6300	5100-6300	1	95.24%
7500	6300-7500	1	100.00%
More	7500 and more	0	100.00%

Looking at this graph it can be said that it is positive(or right)-skewed data.

And positive skew is when the long tail is on the positive side of the peak, and some people say it is "skewed to the right".

The mean is on the right of the peak value.
