Flip the coin $20$ times and record how many heads you get, calculate the proportion of heads. Record the proportions in a spread sheet $($google sheet, excel or csv file, txt file$)2.$ Repeat this process for at least $20$ times and you get $20$ estimate proportions. $3.$ Plot a histogram of all the sample proportions to verify it nearly has a bell shape. $4.$ Calculate the mean and standard deviation of all the sample proportions $($google spreadsheet or excel or python could help you with the calculation easily$)5.$ Verify that the mean from your simulation is close to $0\mathrm{.}5.$
