Answer:
The correct option is a)
05; .73; .27 , type 1 error, type 11 error and the power of the test respectively.
Step-by-step explanation:
Alpha is the probability of a type 1 error, given the null hypothesis is true. Therefore alpha= 0.05
Type 11 error is the probability of accepting a false null hypothesis.
Beta= 0.73
The Power of a test is the probability of rejecting the null hypothesis, given it is false
Power= 1- beta
Power= 1-0.73
Power= 0.27
Therefore the type 1 error is 0.05
The type 11 error is= 0.73
The power of the test= 0.27
The right option is a)
Answer:

Step-by-step explanation:
Answer:
Distributive Property
Step-by-step explanation:
Answer choice a is correct because you are distributing 2 to each term in the parentheses. When you multiply 2 to each factor in the parentheses, it simplifies to 2x-2, thus making the new equation 6x+2x-2=30
Given:
circle inscribed in a square.
Side length of the square = diameter of the circle.
Let x side length and diameter.
Area of a square = x²
Area of a circle = πr²
r = radius ; half of the diameter. = x/2
Area of a circle = π * (x/2)² or π (x²/4)
Ratio of the area of the square to the area of the circle
x² : π(x²/4) or x² / πx²/4
x² * 4/πx² = 4/π
The answer would be b
