Answer:
Check Explanation.
Step-by-step explanation:
The sample will be a representative of the entire build us in the city.
For a sample size 35, 3 have fire code violations, hence, the proportion of houses with fire code violations = (3/35) = 0.0857 = 8.57 %
The uncertainty in the estimate is given in the form of standard error.
Standard error = √[(p(1-p)/n]
n = sample size = 35, p = 0.0857, 1 - p = 0.9143
Standard error of the sample = √(0.0857×0.9143/35) = 0.1616
In terms of the population, (0.1616/35) = 0.00462
Proportion of buildings with fire code violations = (8.57 ± 0.462) %
Hello there,
So the question is asking to change the feet into inches and inorder to that we need to know how many inches go into one feet...
- 1 ft = 12 inch
Now that we know that we need to change the feet into inches by multiplying 12.1 by 12...
The question asked to have the same amount of significant digits as the original...
- the original has 3 and the answer at the moment has 4
Your answer would be 145 inches.
Hope I helped,
Amna
