Answer:
1067
Explanation:
The formula that will be used to calculate the sample size if population proportion isn't given is expressed as;
Sample size n = |Z|² × 0.25/E² where;
Z is the z-score at 95% confidence
E is the margin of error
Given parameters
Z score at 95% confidence interval = 1.96
E = 0.03
Substituting the given values into the formula to get the sample size n we will have;
n = 1.96²×0.25/0.03²
n = 3.8416×0.25/0.0009
n = 0.9604/0.0009
n = 1067.11
n ≈ 1067
Hence, the minimum sample size required to estimate a population proportion is approximately 1067
Answer:
0.5 feet left
Step-by-step explanation:
12 inches = 1 foot
36 inches = ? feet
36 × 1 = 36
12 × ? = 12?
36 = 12?
? = 36/12
? = 3 feet
18 inches = x feet
18/12 = 1.5 feet
3 + 1.5 = 4.5 feet total used
5(total) - 4.5(feet used) = 0.5 feet left
