Continuous Probability Distributions

Probability distributions are of two types, which are continuous probability distributions and discrete probability distributions. A continuous probability distribution contains an infinite number of values. For example, if time is infinite: you could count from 0 to a trillion seconds, billion seconds, so on indefinitely. A discrete probability distribution consists of only a countable set of possible values.

Normal Distribution

Suppose we had to design a bathroom weighing scale, how would we decide what should be the range of the weighing machine? Would we take the highest recorded human weight in history and use that as the upper limit for our weighing scale? This may not be a great idea as the sensitivity of the scale would get reduced if the range is too large. At the same time, if we keep the upper limit too low, it may not be usable for a large percentage of the population!

Question

**Text Transcription for Educational Website:**

66. Inflation: The following graph shows the approximate value of the U.S. Consumer Price Index (CPI) from March 2006 through May 2007.

**Explanation:**
The text introduces a graph that illustrates how the U.S. Consumer Price Index (CPI) fluctuated or changed over a specified period, from March 2006 to May 2007. The CPI is a crucial economic indicator that measures the average change over time in prices paid by consumers for goods and services.

# Higher Order Derivatives: Acceleration and Concavity

## Transcription of Educational Content

The graph displayed illustrates an approximating curve detailing certain data parameters from March 2006 to May 2007.

### Mathematical Context:

1. **Function Definition:**
\[
l(t) = 0.02t^3 - 0.3t^2 + 2t + 200 \quad (0 \leq t \leq 14)
\]
- This function serves as a model to estimate the monthly inflation rates over this period.

### Graph Description:

- **Axes:**
- *X-axis (Jan-07):* Represents time in months, starting from March 2006.
- *Y-axis (199-209):* Represents the CPI (Consumer Price Index) values corresponding to each month.

- **Curve Characteristics:**
- The curve shows a variation in the CPI values over the specified timeline.
- There's an initial increase, peaking between the 6th and 8th month, followed by a dip and another rise nearing the end.

### Questions:

- **(a)** Evaluate the model for monthly inflation estimation.
- **(b)** Assess when the inflation was slowing and speeding up (Hint: See Example 3).
- **(c)** Determine when inflation was accelerating and decelerating.

This information and related graph are crucial for comprehending macroeconomic trends, particularly inflation modeling over a period specified by the dataset. Understanding how inflation accelerates or slows can inform economic strategies and policy decisions.
