Null hypothesis:
Alternative hypothesis
And in order to test this hypothesis we can use a one sample z test for a population proportion and the statistic would be given by:
(1)
And with the data given we have:

Answer:
represents the total perimeter of the table, and if x = 3 the lentgh of entire rubber bumper is 12 feet.
Step-by-step explanation:
Perimeter is defined as the sum of sides.
For a rectangle having dimension length 'L' and breadth 'B' Since, rectangle has two sides equal.
Perimeter of rectangle = 2 ( length + breadth )
Here, given rectangle has dimension
Length = 
and breadth = 
Thus, perimeter of rectangle = 
Thus, perimeter of rectangle is ........(1)
Perimeter of rectangle , when x = 3,
Put x= 3 in (1) ,
Thus, represents the total perimeter of the table, and if x = 3 the lentgh of entire rubber bumper is 12 feet.
