As in the previous problem a fair coin is flipped 68 times If X is the number of heads then the distribution of X can be approximated with a normal distribution N 34 4 1 where the mean is 34 and standard deviation o is 4 1 Using this approximation find the probability of flipping 38 or 39 heads You may use the portion of the Standard Normal Table below Z 0 00 0 01 0 02 0 03 0 04 0 7 0 7580 0 7611 0 7642 0 8 0 7881 0 7910 0 7939 0 7673 0 7704 0 7967 0 7995 0 9 0 8159 0 8186 0 8212 0 8238 0 8264 1 0 0 8413 0 8438 0 8461 0 8485 0 8508 0 8531 0 8554 0 8577 0 8599 0 8621 1 1 0 8643 0 8665 0 8686 0 8708 0 8729 0 8749 0 8770 0 8790 0 8810 0 8830 1 2 0 8849 0 8869 0 8888 0 8907 0 8925 0 8944 0 8962 0 8980 0 8997 0 9015 1 3 0 9032 0 9049 0 9066 0 9082 0 9099 0 9115 0 9131 0 9147 0 9162 0 9177 Round the final answer to two decimal places Provide your answer below 0 05 0 06 0 07 0 08 0 09 0 7734 0 7764 0 7794 0 7823 0 7852 0 8051 0 8078 0 8106 0 8133 0 8023 0 8289 0 8315 0 8340 0 8365 0 8389
