The result will show the mean value of two teams, Variance Value, how many observations are conducted or how many values taken into consideration, Pearson Correlation etc…
If you P (T<=t) two tail it is 0.314 which is higher than the standard expected P value of 0.05. This means data is not significant.
We can also do the T-test by using built-in function T.TEST.
SOLVER Option – Example#2
A solver is nothing but solving the problem. SOLVER works like a goal seek in excel.
Look at the below image I have data of product units, units price, total cost, and the total profit.
Units sold quantity is 7550 at a selling price of 10 per unit. Total cost is 52500 and the total profit is 23000.
As a proprietor, I want to earn a profit of 30000 by increasing the unit price. As of now, I don’t know how much units price I have to increase. SOLVER will help me to solve this problem.
Step 1: Open SOLVER under DATA tab.
Step 2: Set the objective cell as B7 and the value of 30000 and by changing the cell to B2. Since I don’t have any other special criteria’s to test I am clicking on the SOLVE button.
Step 3: The Result will be as below:
Ok, excel SOLVER solved the problem for me. To make a profit of 30000 I need to sell the products at 11 per unit instead of 10 per unit.
In this way, we can do the analyze the data.
