1 point) Suppose we will flip a fair coin 100 times. Let X be the number of heads, and use a Normal distribution to approximate the distribution of X. (a) Apply the continuity correction: P(42≤X≤58)= P( -8/5 0 )

Step-by-step explanation:

When a fair coin is tossed 100 times X no of heads is binomial with n =100 and p = 0.50

Mean = np = 50 and Variance = npq = 25

so std dev = 5

When approximated to normal

X : no of heads : N(50,5)

Required probability

i) (applying continuity correction_

= F(58.5) -F(41.5)

= 0.9554-0.0446

=0.9108

ii)

c)

d) P(X>0)

=1-0.0000

=1

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
