I suppose to estimated how many corn Kernel are in a a 2 litter bottle could some one help me please. Thank You
please also show an equation for finding the number

I'd compute the volume of a random sample of individual kernels. Then get the average, and standard deviation, then remember that 68% of a population will be within one standard deviation of the average. Then get the volume of the 2 liter bottle, and do some division.
