We flip a coin 100 times (n = 100)and note that it only comes up heads 20% (p = 0.20)of the time. The mean and standard deviation for the number of times the coin lands on heads is μ = 20and σ = 4 (verify the mean and standard deviation). Solve the following. (Round your percents to two decimal places.)

(a) There is about a 68% chance that the number of heads will be somewhere between __________ (smaller value) and___________   (larger value). 

(b) There is about a _____  % chance that the number of heads will be somewhere between 12 and 28. 

(c) There is about a  _______ % chance that the number of heads will be somewhere between eight and 32.
