10. divide the problems below among your group, and find the sample proportion of successes and the estimated margin of error in each situation:
a. sample of size 20, 5 red chips
b. sample of size 40, 10 red chips
c. sample of size 80, 20 red chips
d. sample of size 100, 25 red chips

a) 0.1936

b) 0.137

c) 0.097

d) 0.087

Step-by-step explanation:

Margin of error is given as:

E =  

here,

p is the probability of event

n is the sample size

a. Sample of size 20, 5 red chips

n = 20

p = 5 ÷ 20

= 0.25

Thus,

E =  

or

E = 0.1936

b. Sample of size 40, 10 red chips

n = 40

p = 10 ÷ 40

= 0.25

Thus,

E =  

or

E = 0.137

c. Sample of size 80, 20 red chips

n = 80

p = 20 ÷ 80

= 0.25

Thus,

E =  

or

E = 0.097

d. Sample of size 100, 25 red chips

n = 100

p = 25 ÷ 100

= 0.25

Thus,

E =  

or

E = 0.087

konichiwa~! my name is zalgo and i am here to answer your anime-related question today. more than likely, kirishima would kill izuku, marry mino and kiss momo. all of this would be my opinion by the way. (and i am also a weeb lol)
