Concept explainers

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.

### Statistical Hypothesis Testing Example

Twenty years ago, 56% of parents of children in high school felt it was a serious problem that high school students were not being taught enough math and science. A recent survey found that 247 out of 700 parents of children in high school felt it was a serious problem. Do parents feel differently today than they did twenty years ago? Use the $\alpha = 0.01$ level of significance.

#### Hypotheses:

- Null hypothesis ($H_0$): $p = 0.56$
- Alternative hypothesis ($H_1$): $p \neq 0.56$

*Note: $p$ represents the proportion of parents who are concerned.*

#### Test Statistic Calculation:

The calculated test statistic is:

\[ z_0 = -11.04 \]

*Round to two decimal places as needed.*

#### P-value:

The P-value is determined based on the test statistic value.

*Round to three decimal places as needed.*
