Based on the above scenario, the sales director conducted an <u>experiment</u>.

Because a treatment <u>was </u>applied to the sales representatives.

The the best statistical study for this situation because the sales director is trying to establish <u>correlation</u>.

<h3>What is an experiment?</h3>

An experiment is known to be a method that is et up with the aim to test a given hypothesis as a component of a scientific method.

In an experiment, there are the two key variables which are the independent and dependent variables. The independent variable is known to be a controlled or it is tested against the dependent variable.

Solve a=2b-c for b<br><br> Can someone help me

Sauron [17]

Answer:

$b=\frac{a}{2} +\frac{c}{2}$

Explanation:

While solving literal equations could be quite overwelhming, simply solve it by using normal equation solving methods.

For example, if you were to solve 2x + 3 = 9

You would add 3 on both sides and divide both sides by 2 to determine x.

Do the same thing for literal equations, and if in doubts, plug in numbers to check your work.

Step-by-step explanation:

For this problem, add c on both sides, we do this because we are aiming to eliminate the c from both sides.

a+c =2b

In order to find the value of b, divide both sides by 2, we do this because we want to get rid of the coefficient.

This should leave you with the answer of b=a/2 + c/2

Here is the histogram of a data distribution. All class widths are 1.

stich3 [128]

The median of the data is 5 if the all class widths are 1, option (C) is correct.

<h3>What is the median?</h3>

A median is a middle number in a series of numbers that have been arranged to lift, and it might be more informative of the set of data than the average. When there are extremes in the sequences that might affect the average of the numbers, the median is sometimes employed instead of the mean.

In the histogram, 15 data values are given:

1, 2, 2, 3, 3, 3, 4, 5, 6, 6, 7, 7, 7, 8, 9

The mid-value is 5 which is on the 8th place

Thus, the median of the data is 5 if the all class widths are 1, option (C) is correct.
