We conclude the hypothesis test as Alternative Hypothesis if the data would be very unusual if the original assumption about our parameter were correct.
- A hypothesis in statistics is a claim or supposition on the properties of one or more variables in one or more populations. There are two hypothesis to choose between because a statement might either be true or wrong.
- The null hypothesis is the assertion that we (or someone else) consider to be true. Our hypothesis test will come to one of two conclusions: "reject H0" or "do not reject H0." Remember that until data provide evidence to the contrary, we always proceed under the null hypothesis.
- If the null hypothesis is incorrect, the alternative hypothesis must be true. The hypothesis test can be different in one of three ways: greater than, smaller than, or just different (not equal). As a result, there will always be an inequality requirement in the notation for H.

The ratio of the geeses to ducks will be 11:12 because there are 11 geeses and 12 ducks :)
Answer:
8 12 = 0.6667
Step-by-step explanation:
How to Calculate 1/4 Divided by 3/8
1 4 / 3 8.
1 4 x 8 3.
1 x 8 4 x 3 = 8 12.
the answer is 8 12 = 0.6667.
Answer: 2.4 pounds of the type of nut that sells for $3.00/lb and 4.8 pounds of the type of nut that sells for $5.40/lb would be needed.
Step-by-step explanation:
Let x represent the number of pounds of the type of nut that sells for $3.00/lb that you would need.
Let y represent the number of pounds of the type of nut that sells for $5.40/lb that you would need.
You would like to have 7.2 lbs of a nut mixture. It means that
x + y = 7.2
The mixture would sell for $4.60/lb. It means that the cost of the mixture would be
4.6 × 7.2 = $33.12
This means that
3x + 5.4y = 33.12- - - - - - - - - 1
Substituting x = 7.2 - y Intl equation 1, it becomes
3(7.2 - y) + 5.4y = 33.12
21.6 - 3y + 5.4y = 33.12
- 3y + 5.4y = 33.12 - 21.6
2.4y = 11.52
y = 11.52/2.4
y = 4.8
x = 7.2 - y = 7.2 - 4.8
x = 2.4
complete question:
The green area in the figure above represents a section of grass for a putting green. Find the area of the sector of grass.
A. A= 32π ft²
B. A= 6π ft²
C. A= 36π ft²
D. A= 72π ft²
Answer:
C. A= 36π ft²
Step-by-step explanation:
The image below is where your question emanated. The area of the sector of grass can be calculated below.
Area of a sector = ∅/360 × πr²
where
∅ = angle from the center of the circle
r = radius
Area of a sector = ∅/360 × πr²
r = 12 ft
∅ = 90°
Area of a sector = 90/360 × π × 12²
Area of a sector = 90/360 × π × 144
Area of a sector = 1/4 × 144π
Area of a sector = 144π/4
Area of a sector = 36π ft²
