Which statement implies that A and B are independent events?A. P(B|A) = P(B A)
B. P(B|A) = P(B)
P(A)
C. P(B|A) = P(A)
D. P(B|A) = P(B)
Answers
The events are independent if and only if
. Under this condition, we have conditional probabilities
so the answer is D.

Answer:
e= 2
W= 15
m= 9
Step-by-step explanation:
for e: yout multiply 5 x 7 to get 35 so 2 x 7 = 14
for W: 20/10 = 2 so divide 30/2 to get 15
for m: 11 x 2 = 22 so do 18 divided 2 to get 9
Answer:
E = 2
W = 15
M = 9
Step-by-step explanation:
You just have to make the denominator / numerator the same.
=
Multiply the first fraction by 7 so that their denominators are both 35.
=
7E = 14
E = 14 ÷ 7
E = 2
=
Multiply the second fraction by 2 so that their numerators are both 20.
=
2W = 30
W = 30 ÷ 2
W = 15
=
Multiply the first fraction by 2 so that their denominators are both 22.
=
2M = 18
M = 18 ÷ 2
M = 9
-14 = 4a
Answers
Answer:
a = -3 1/2
Step-by-step explanation:
To solve the equation for a, divide each side by 4.
-14 = 4a
-14/4 = 4a/4
-14/4 = a
Simplify the fraction by dividing the top and bottom by 2.
-7/2 =a
This is an improper fraction, so change to a mixed number.
2 goes into 7 3 times with 1 left over.
-7/2 = -3 1/2
a = -3 1/2
-14=4a

To use a z-procedure to construct a confidence interval for a population proportion, the following conditions must be met:
D) The sample must be random and sufficiently large.
This means that the sample should be selected in a way that each individual has an equal chance of being included. Additionally, the sample size should be sufficiently large to ensure that the normal approximation for the sampling distribution of the sample proportion is valid.
It's important to have a random sample because it helps to ensure that the sample is representative of the population, making the results more reliable and generalizable.
As for the sample size, it should be large enough to satisfy the condition of having at least 10 successes and 10 failures. This ensures that the normal approximation can be applied.
The other answer choices, A) The sample size must be small, B) The population standard deviation must be known, and C) The population must be normally distributed, are incorrect and do not apply to the conditions for using a z-procedure to construct a confidence interval for a population proportion.
By meeting the conditions of having a random and sufficiently large sample, you can use a z-procedure to construct a confidence interval for a population proportion.Answer:

Answer:
0.75 inches
Step-by-step explanation:
The value that has z=2 is 2 standard deviations from the mean. The value that has z=1 is 1 standard deviation from the mean. The difference between these two values is 1 standard deviation:
1 standard deviation = 3.75 in - 3 in = 0.75 in
