Answer:
A=0, B=2, C=4, D=6 and E=7.
Step-by-step explanation:
It is given that the number line goes from 0 to 9.
The whiskers range from 0 to 7, indicated by A and E. It means
A = 0 and E = 7
The box ranges from 2 to 6, indicated by B and D. It means
B = 2 and D = 6
The line divides the box at 4, indicated by C. It means
C = 4
The box plot is shown below.
Therefore, the location of the values used to create a box plot are A=0, B=2, C=4, D=6, E=7.

Answer:
The standard error of the proportion is 0.0367.
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean and standard deviation
, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean
and standard deviation
.
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
For a proportion p in a sample of size n, the standard error is
In this question:
So
The standard error of the proportion is 0.0367.
