Now certain information that would be necessary for this survey can be included as questions and to analyze the data each and every option is compared with other choices. This can be compared using pie charts or histograms

The answer to this question would be 3%
The answer is 10 pounds.
I set up a proportion of 10 / 0.01 = 10000 / x.
Cross-multiply to get 10x = 10000(0.01). Simplify to get 10x = 100. Divide by 10 to isolate the variable.
x = 10. 10000 samples would weigh 10 pounds.
