Answer:
the x² test statistic 13.71
Option a) 13.71 is the correct answer.
Step-by-step explanation:
Given the data in the question;
Feeder 1 2 3 4
Observed visits; 
60 90 92 58
data sample = 300
Expected 
= 300 / 4 = 75
the x² test statistic = ?
= ∑[ ( - )²/]
= [ (60 - 75)² / 75 ] + [ (90 - 75)² / 75 ] + [ (92 - 75)² / 75 ] + [ (58 - 75)² / 75 ]
= [ 3 ] + [ 3 ] + [ 3.8533 ] + [ 3.8533 ]
= 13.7066 ≈ 13.71
Therefore, the x² test statistic 13.71
Option a) 13.71 is the correct answer.
Answer:
Parallel lines
Step-by-step explanation:
x - y = 1 y - x = 1
- y = -x + 1 y = x + 1 ⇒ m₂ = 1, b₂ = 1
÷(-1) ÷(-1)
y = x - 1 ⇒ m₁ = 1, b₁ = -1
m₁ = m₂ and b₁ ≠ b₂ means that the lines described by these equations are parallel
Answer:
D) 29.41 oz
Step-by-step explanation:
Maya has 15 cousins, which means she is making 15 bags.
She has 441.15 oz of candy in all. Divide 441.15 with 15:
