Answer:
H is the Answer
Step-by-step explanation:
Apply distance formula.

where d is the distance.




19 you could’ve just used the calculator lol
1/2 and 1/3 are similar because 3/6 and 2/6 are similar. They are so close but not the same.
Margin of error, e = Z*SD/Sqrt (N), where N = Sample population
Assuming a 95% confidence interval and substituting all the values;
At 95% confidence, Z = 1.96
Therefore,
0.23 = 1.96*1.9/Sqrt (N)
Sqrt (N) = 1.96*1.9/0.23
N = (1.96*1.9/0.23)^2 = 262.16 ≈ 263
Minimum sample size required is 263 students.
it have manny solution it depand on a method u are using
