The sample size must be 543 so the sample proportion is will not differ by 5%
We are given the following in the question:
Margin of error = 5%
Confidence interval:
p ±z√(p'(1 - p')/n)
Margin of error =
p = ±z√(p'(1 - p')/n)
Since no particular proportion is given, we take
p' = 0.5
Z critical at α 0.02 is ± 2.33
Putting values, we get,
p = ±z√(p'(1 - p')/n)
2.33 x √(0.5(1 - 0.5)/n)
√n = 2.33x 0.5/0.05
n = 542.89 = 543
Thus, the sample size must be 543 so the sample proportion is will not differ by 5%

Answer:
Step-by-step explanation:.75r = 26 + .75r
r = 26
1 sixths would be the awnser you just take away four from five that will give you one so you just need to add the sixths part
Answer:
14
Step-by-step explanation:
2×5+2(0+2)
Multiply 2 and 5 to get 10.
10+2(0+2)
Add 0 and 2 to get 2.
10+2×2
Multiply 2 and 2 to get 4.
10+4
Add 10 and 4 to get 14.
