The planning value for the population standard deviation is 4330.
Given the confidence interval 20000 and 35000.
We have to find the planning value of standard deviation.
Standard deviation is measuring dispersion of data. Uniform probability distribution has two bounds a and b. The standard deviation is given by :
s=.
Annual starting salaries for college graduates be between 20000 and 35000.
It is uniform in the interval so, a=20000, b=35000.
Now we have to just put the values of a and b in the above formula to get the value of standard deviation.
s=
=
=
=
=4330
Hence the planning values for the population standard deviation is 4330.

Answer:
The ratio of blue balloons to the total number of balloons is 1:2.
Step-by-step explanation:
Given:
Total number of balloons = 14
Number of red balloons = 3
number of white balloons = 4
Number of the blue balloons are the rest remaining.
We need to find the the ratio of blue balloons to the total number of balloons.
Solution:
First we will find the number of blue balloons.
Now we know that;
Number of the blue balloons can be calculated by Total number of balloons minus sum of Number of red balloons and number of white balloons.
framing in equation form we get;
Number of the blue balloons =
Now to find the ratio of blue balloons to the total number of balloons we will divide Number of the blue balloons from Total number of balloons.
framing in equation form we get;
Ratio =
Hence the ratio of blue balloons to the total number of balloons is 1:2.
