Answer:
it is true
Step-by-step explanation:
A test statistic compares our observed outcome to the alternative hypothesis. If the null hypothesis is true, then the teststatistic will be close to 0. Therefore, the farther the test statistic is from 0, the more the null hypothesis is discredited.

Answer:
102
75%
25%
Step-by-step explanation:
In a box plot,
There are 5 values:
Min (38)
Q1 (72)
Q2 (88)
Q3 (96)
Max (102)
Between 2 consecutive quartiles, there's 25% data
Above 72 is ¾ data
¾ × 100 = 75%
Between 88 and 96, is ¼ data
¼ × 100 = 25%
P (0.5<= V <=0.54) (±0.0001)=
(b) In fact, 50% of the respondents said they planned to vote for Barack Obama V = 0.5. If respondents answer truthfully, What is P(V <=0.5)?
P (V <=0.5) (±0.0001) =
Answer:
a) 97.37%
b) 1.31%
Step-by-step explanation:
a)
Here we want to calculate the area under the Normal curve with mean 0.52 and standard deviation 0.009 between 0.5 and 0.54
This can be easily done with a spreadsheet and we get
P (0.5くV < 0.54) = 0.9737 or 97.37%
(See picture 1)
b)
Here we want the area under the Normal curve with mean 0.52 and standard deviation 0.009 to the left of 0.5.
P(V ≤ 0.5) = 0.0131 or 1.31%
(See picture 2)
9*8=72
72-5=67
The final answer is 67.

Answer:
Step-by-step explanation:
The diameter of the circle is twice the radius, so the diameter of the circle is 2 x 12 inches = 24 inches.
To find the area of the circle, we can use the formula A = πr^2, where A is the area of the circle and r is the radius.
So, for this circle, A = π(12 inches)^2 = 144π square inches.
Therefore, the diameter of the circle is 24 inches, the formula to find the area of the circle is A = πr^2, and the area of the circle is 144π square inches.
Answer: 144 pie square inches!
Step-by-step explanation:
1st blank : is 24 square inches since the radius which is half the diameter is 12 square inches we can easily know that the diameter would be 24 square inches!
2nd blank : pie r squared is the formula! for all areas of the circles! the total length in other words the circumference of the circle would be 2 pie r basically multiplying 2 and pie and the radius.
3rd blank : the area of the circle is 144 pie (square inches)!
