Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.

Monthly working hours of A and B Machines are given below. Find the result of the calculation regarding whether there is a difference between the working hours.
Here machines A and B are independent but we do not know whether the data is Normal distribution or not
So , we will use non-parametric method i.e. Wilcoxon Rank-Sum Test Calculator
Given Data :
| = Machine A | = Machine 2 |
| 35 | 85 |
| 42 | 72 |
| 54 | 26 |
| 75 | 46 |
| 48 | 95 |
Now, we will organize both the samples in ascending order :
| Sample | Value |
| 2 | 26 |
| 1 | 35 |
| 1 | 42 |
| 2 | 46 |
| 1 | 48 |
| 1 | 54 |
| 2 | 72 |
| 1 | 75 |
| 2 | 85 |
| 2 | 95 |
Now, assigning ranks for the ordered data above (assigning the average rank to values with rank ties )
| Sample | Value | Rank | Rank (Adjusted for ties) |
| 2 | 26 | 1 | 1 |
| 1 | 35 | 2 | 2 |
| 1 | 42 | 3 | 3 |
| 2 | 46 | 4 | 4 |
| 1 | 48 | 5 | 5 |
| 1 | 54 | 6 | 6 |
| 2 | 72 | 7 | 7 |
| 1 | 75 | 8 | 8 |
| 2 | 85 | 9 | 9 |
| 2 | 95 | 10 | 10 |
