Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
![A previous survey asked people whom they would consult for an ankle. The following results were
obtained: 40% said they would consult their doctor; 38% said they would consult a physical
therapist; 12% said they would consult a chiropractor; and 10% said they would simply rest at home
and stay off it for a few days.
You think that this model is no longer valid, so you decide to conduct a survey and find out for
yourself. Relying on knowledge you gained in CMP 114, your favorite class of all time, you test the
results to see if your hunch was right. Your survey produced the following results:

The hypothesis is,
Null hypothesis:
The model is valid.
Alternative hypothesis:
The model is no longer valid.
The expected count is,
| Category | Count | Proportion | Expected count |
| Doctor | 94 | 0.40 | |
| PT | 80 | 0.38 | |
| Chiropractor | 16 | 0.12 | |
| Stay At Home | 10 | 0.10 | |
| Total | 200 |
The chi-squared test statistic value is,
Thus, the chi-squared test statistic value is 10.3272.
