We flip a coin 100 time
(n = 100)
and note that it only come up head 20%
(p = 0. 20)
of the time. The mean and tandard deviation for the number of time the coin land on head i
= 20
and
= 4
(verify the mean and tandard deviation). Solve the following. (Round your percent to two decimal place. )
(a) There i about a 68% chance that the number of head will be omewhere between (maller value) and (larger value). (b) There i about a % chance that the number of head will be omewhere between 12 and 28. (c) There i about a % chance that the number of head will be omewhere between eight and 32
