Concept explainers

Quadratic Equation

When it comes to the concept of polynomial equations, quadratic equations can be said to be a special case. What does solving a quadratic equation mean? We will understand the quadratics and their types once we are familiar with the polynomial equations and their types.

Demand and Supply Function

The concept of demand and supply is important for various factors. One of them is studying and evaluating the condition of an economy within a given period of time. The analysis or evaluation of the demand side factors are important for the suppliers to understand the consumer behavior. The evaluation of supply side factors is important for the consumers in order to understand that what kind of combination of goods or what kind of goods and services he or she should consume in order to maximize his utility and minimize the cost. Therefore, in microeconomics both of these concepts are extremely important in order to have an idea that what exactly is going on in the economy.

### Study of the Costa Rican Three-wattled Bellbird

**Background:**
Males of the Costa Rican three-wattled bellbird are reported to be the world's loudest birds. Their calls can be heard over half a mile away, with claims of their calls reaching 100 decibels (dB). Juanita, a Costa Rican, doubts the accuracy of this claim and decides to conduct a hypothesis test with a sample of nine adult males.

### Hypothesis Testing

**Assumptions:**
- The loudness of bellbird songs is approximately normally distributed with unknown mean (μ) and variance (σ²).

**Hypotheses:**
1. $ H_0: \mu = 100, H_A: \mu \leq 100 $
2. $ H_0: \mu = 100, H_A: \mu < 100 $
3. $ H_0: \mu = 100, H_A: \mu \neq 100 $
4. $ H_0: \mu = 100, H_A: \mu > 100 $
5. $ H_0: \mu \leq 100, H_A: \mu > 100 $

### Results

**Data:**
- Average loudness: 94.619 dB
- Variance: 49.0001 dB²

**Tasks:**

1. **Choice of Test (ii):**
- Conduct a hypothesis test using the data and report the p-value.
- Decide whether to accept or reject $ H_0 $ at a 2% significance level ($ \alpha = 0.02 $).

2. **Confidence Interval (iii):**
- Construct a 95% confidence interval for μ.
- Interpret the interval.

3. **Sample Size Calculation (iv):**
- Determine the sample size required to have a margin of error of at most 5 in the confidence interval.

4. **Statistical Analysis Without Formal Training (v):**
- Juanita assumes sample variance equals population variance.
- Determine her p-value and decision about $ H_0 $ at the 2% significance level.

5. **Expansion of Sample Size (vi):**
- Consider the impact of a larger sample size, say around 50, on the results.
- Discuss why and how results may vary.
