Answer:
the smallest sample size is 163
Step-by-step explanation:
The computation of the smallest sample size that meets these criteria is shown below:
n = (Z a/2 × Standard deviation ÷ Margin of error ) ^2
Zα/2 at 0.05% LOS is = 1.96 ( From Standard Normal Table )
Standard Deviation ( S.D) = 2.6
Margin of error i.e. ME =0.4
n = ( 1.96 × 2.6 ÷ 0.4) ^2
= 163
Hence, the smallest sample size is 163

Answer:
6000 yard² of area is not covered by the tent.
Step-by-step explanation:
The question is "A rectangular field is 120 yards long and 53 yards wide. A tent that is 20 yards long and 18 yards wide covers part of the field. How many square yards of the field are not covered by the tent."
Given that,
Length of a rectangular field = 120 yards
Breadth of a rectangular field = 53 yards
Area of rectangular field = l×b
= 120 × 53
= 6360 yard²
Length of a tent = 20 yards
Breadth of the tent = 18 yards
Area of the tent = lb
= 20 × 18
= 360 yards²
Area not covered = 6360 yard² - 360 yards²
= 6000 yard²
So, 6000 yard² of area is not covered by the tent.
