Answer: n = 2401
Step-by-step explanation:
Given;
Confidence level = 2% - 99%
n = ? ( which is the sample size is unknown ).
Solution:
Where;
n = [z/E]^2*pq
Since no known value for ( p ) estimate is given, the "least biased" estimate is p = 1/2
Substituting the given data into the formula.
n = [1.96/0.02]^2(1/2)(1/2)
n = 2401
The minimum number of truck drivers the statistician needs to sample for an accurate result is 2401
Answer:
No because 50 cm would be short of 14 cm required to cover the total perimeter
Step-by-step explanation:
2 meter long string into 4 equal part
1 part = 50 cm
Side length of the square = 16
16 × 4 = 64cm ⇔ Perimeter of the square box
50 < 64
