When you multiply both sides by a negative value you make the side that is greater have a "bigger" negative number, which actually means it is now less than the other side! This is why you must flip the sign whenever you multiply by a negative number.
Answer:
The estimated value for the population standard deviation is $3,750.
Step-by-step explanation:
The interval within which the annual starting salaries for college graduates with degrees in business administration are generally expected to be is $30,000 and $45,000.
The standard deviation is the measure of dispersion or spread. And so is the range of the data.
Both the measures are used to determine how spread out the data is from the mean.
The relationship between standard deviation and range is not defined but according to the rule of thumb the standard deviation is one-fourth of the range of the data.
The formula of range is:

Compute the range of the data of starting salaries of college graduates with degrees in business administration as follows:

The range of the data is, $15,000.
Compute the estimated value of the standard deviation as follows:

Thus, the estimated value for the population standard deviation is $3,750.
Equation is given as;
y = (g/k) yo
To find the value of “k”, divide both sides of the
equation with yo;
y/yo = (g/k)yo/yo
it implies that;
y/yo = (g/k)
Now following steps will obtain the value of “k” as;
ky/yo = g
ky = gyo
<span>k = gy0/y </span>
