Hope this helped! I’d appreciate brainless answer!
Answer:
Step-by-step explanation:
(a) H0: μ_D=0
Ha: μ_D ≠ 0
b) Find attached the solution
(c) By technology,
p - value = 0.4437
Hence,
the p-value is 0.4437
Probability is the likelihood or chance that an event will occur. The complement of the probability will be 0.95
<h3>What is probability?</h3>
Probability is the likelihood or chance that an event will occur. Mathematically:
Probability = expected outcome/total outcome
Given that the probability of an event is P(A) = 0.05, the complement will be expressed as:
P'(A) = 1 - P(A)
P'(A) = 1 - 0.05
P' (A) = 0.95
Hence the complement of the probability will be 0.95

To find the product, we can multiply all 3 numbers.
= -6 × -7 × -1
= 42 × -1 (Anytime you multiply 2 negative numbers, it results in a positive number.)
= -42
Let thd centre be O
Draw a line joining B and C
Angle OCB= 46 (alternate angles)
Angle COB= 180-46-46= 88
Angle BOA= 180-88-46=46
46 =x+4
x=42
