Transcribed Image Text:### Statistical Hypothesis Testing
1. **Identify the Null and Alternative Hypothesis in Symbolic Form**
- A certain car company develops a car that will average better than 35 miles per gallon (mpg).
- **Null Hypothesis (\( H_0 \))**: \(\mu \leq 35\) mpg
- **Alternative Hypothesis (\( H_a \))**: \(\mu > 35\) mpg
- This represents the original claim that the car averages better than 35 mpg.
2. **Find \( z_{\alpha} \) for \( \alpha = 0.02 \)**
- Conduct a one-tail test.
- (**Graph explanation**: A standard normal distribution curve is typically drawn. Shade the tail corresponding to \( \alpha = 0.02 \) on the right side of the curve to represent the rejection region.)
3. **Find the \( p \)-value for a Right-Tailed Test**
- Given that the test statistic is \( z = 1.02 \).
- (**Graph explanation**: Again, draw a standard normal distribution curve. Mark the point \( z = 1.02 \) and shade the area to the right of this point to represent the \( p \)-value for the right-tailed test.)
