1. different students drew random samples of size 50 from the mystery bag. the number of red chips each drew is given below. in each case, find the margin of error for the proportions
of the red chips in the mystery bag.
a. 10 red chips
b. 28 red chips
c. 40 red chips

Part A:

Margin of error=M≅0.1131

Part B:

Margin of error=M≅0.1404

Part C:

Margin of error=M≅0.1131

Step-by-step explanation:

The formula for finding the margin of error for the proportion  is:

Margin of error=M=

where:

p is the sample proportion =

n is the sample size

Part A:

Margin of error=M=

p=

p=0.2

Margin of error=M=

Margin of error=M≅0.1131

Part B:

p=

p=0.56

Margin of error=M=

Margin of error=M≅0.1404

Part C:

p=

p=0.8

Margin of error=M=

Margin of error=M≅0.1131

36/60

36/2=18

60/2=30

18/30

18/3=6

30/3=10

6/10

6/2=3

10/2=5

your final answer would be 3/5 of an

hope this !

a precentage of 6th graders. the population is all 6th graders. let me know if i'm wrong, i hope this ! : )
