Modify the program CoinTosses so that it tosses a coin [math]n[/math] times and records whether or not the proportion of heads is within .1 of .5 (i.e.,between .4 and .6). Have your program repeat this experiment 100 times. About how large must [math]n[/math] be so that approximately 95 out of 100 times the proportion of heads is between .4 and .6?
