Answer:
option (b) df = 1, 24
Step-by-step explanation:
Data provided in the question:
levels of factor A, a = 2
levels of factor B, b = 3
Subjects in each Sample, s = 5
n = 5 × 3 × 2 = 30
Now
df for Factor A = a - 1
= 2 - 1
= 1
df for Factor B = b - 1
= 3 - 1
= 2
df for Interaction AB = ( a - 1 ) × ( b - 1 )
= 1 × 2
= 2
df for Total = n - 1
= 30 - 1
= 29
df for error = 29 - 5
= 24
Hence,
df values for the F-ratio evaluating the main effect of factor A is 1, 24
The correct answer is option (b) df = 1, 24
Answer:
13 pounds of grass.
Step-by-step explanation:
You need 20 pounds of grass seed to plant inside the baseball diamond.
The Baseball Diamond is a square of side = 90 ft
The Softball Diamond is a square of side = 60 ft
The ratio of the size of the Baseball Diamond to that of Softball Diamond is:
90: 60 = 3:2
If 3 represents 20 pounds, then 2 represents;
× 20 = 13.33333333 pounds = 13 pounds (rounded to nearest pound)
For the first one, we add 2.7 to both sides to get x≥13. Next, we divide both sides by -0.84 to get x≥ 168/-0.84. SInce we multiplied or divided by a negative number, we switch the sign around and end up with x≥200
That would be 7.
