a. If random sample of 144 current stockholders is taken, what is the probability that more than 15% of them will find offer teams attractive?
b. If random sample of 100 current stockholders is taken, what is the probability that less than 24% of them will find offer teams attractive?
c. If random sample of 81 current stockholders is taken, what is the probability
that less than 74% of them will not find offer teams attractive?
d. If random sample of 100 current stockholders is taken, what is the probability that more than 60% of them will not find offer teams attractive?
