Concept explainers

Angles in Circles

Angles within a circle are feasible to create with the help of different properties of the circle such as radii, tangents, and chords. The radius is the distance from the center of the circle to the circumference of the circle. A tangent is a line made perpendicular to the radius through its endpoint placed on the circle as well as the line drawn at right angles to a tangent across the point of contact when the circle passes through the center of the circle. The chord is a line segment with its endpoints on the circle. A secant line or secant is the infinite extension of the chord.

Arcs in Circles

A circular arc is the arc of a circle formed by two distinct points. It is a section or segment of the circumference of a circle. A straight line passing through the center connecting the two distinct ends of the arc is termed a semi-circular arc.

**Tractor Skidding Distance Analysis**

A recent study investigated tractor skidding distances along a road in a forest. The skidding distances (in meters) were measured at 20 randomly selected road sites. The data are given in the accompanying table. A logger working on the road claims that the mean skidding distance is at least 425 meters. Is there sufficient evidence to refute this claim? Use $\alpha = 0.10$.

### Hypothesis Test
State the hypotheses to test if there is sufficient evidence to refute the claim that the mean skidding distance is at least 425 meters. Choose the correct answer below.

- **A.**
- $H_0$: $\mu = 425$
- $H_a$: $\mu < 425$
- **B.**
- $H_0$: $\mu = 425$
- $H_a$: $\mu \neq 425$
- **C.**
- $H_0$: $\mu = 425$
- $H_a$: $\mu > 425$
- **D.**
- $H_0$: $\mu \neq 425$

### Data Table
The skidding distances recorded at 20 randomly selected road sites are as follows:

| 492 | 348 | 457 | 203 | 286 |
|-----|-----|-----|-----|-----|
| 399 | 423 | 565 | 440 | 549 |
| 389 | 289 | 183 | 260 | 272 |
| 399 | 315 | 310 | 140 | 416 |

**Calculate the value of the test statistic:**

\[ t = \text{(Round to two decimal places as needed.)} \]

When conducting a hypothesis test regarding the mean skidding distance, use the given data to determine whether there is substantial evidence to refute the logger's claim. Following standard procedures, calculate the sample mean and standard deviation, then use these values in the test statistic formula for a one-sample t-test.
