Answer: 5 yards of green felt and 4 yards of blue felt is used to make each quilt.
Step-by-step explanation:
As per given ,
Length of green felt used to make 3 quilts = 15 yards
Then , the length of green felt used to make 1 quilt =
Length of blue felt used to make 3 quilts = 12 yards
Then , the length of blue felt used to make 1 quilt =
Hence, 5 yards of green felt and 4 yards of blue felt is used to make each quilt.

Test statistic:
here test statistic lie in rejection region,that why null hypothesis fails
so Yes, its significant.
b)
Test statistic:
c)
sample variability increases, therefore likelihood of rejecting the null hypothesis decreases.
Since the area of a square is equal to the square of one of its side's length, then the area should be equivalent to 
.
---> equation (1)
By using pythagoras rule which states that the
---> equation (2)
where the opposite side's length is 8 and the hypotenuse side's length is 10
by substituting by the values in equation (2) therefore,
substitute this value in equation (1) then
where A is the area of the square whose side is x
