In problem 4.2-25 we have all of these elements. Credit Cards: Twenty eight percent of college students say they use credit cards because of the rewards programs. You select 10 college students and ask each to name the reason he or she uses credit cards. Find the probability that the number of college students who say they use credit cards because of the rewards program is
a) Exactly 2 = P(exactly 2)=25.48%
b) More than 2 = P(more than 2)= P(3)+P(4)+ P(5)+P(6)+ P(7)+P(8)+ P(9)+P(10)=56.22%
c) Between 2 and 5 (inclusive) = P(2)+P(3)+P(4)+P(5)=78.28%
Look at the Minitab tutorial for week4 Binomial All in One. Follow those steps and answer the questions.
d) Exactly 4
e) More than 4
f) Less than 4
g) 4 or More
h) 4 or less
i) Between 4 and 6 inclusive
