Question
The standard deviation for all medium size hot dogs is 49.99 calories. A random selection of 55 different brands of medium size hot dogs has a mean of 239 calories. Comfort Food Magazine states the mean calories of a medium size hot dog size is 233. Is there sufficient evidence to conclude that the mean calories of a medium size hot dog is 233 based on level of significance of 0.03?
![### Transcription and Explanation
#### Finding Critical Values (CV)
- **Question**: To find our Critical Value(s) (CV), will we use invNorm(), invT()?
- **Options**:
- Dropdown menu option: `invNorm()`
#### Explanation
- **Question**: Please explain the reason for the correct answer for step c.
- **Answer**: The population standard deviation is given (σ).
#### Calculation
- **Instruction**: Round to Two Decimal Places
- **CV1**: [Input Box]
- **CV2**: [Input Box]
#### Formula Selection
- **Question**: What formula will we use for the test value?
- **Options**:
1. \( t = \frac{\bar{x} - \mu}{\frac{s}{\sqrt{n}}} \)
2. \( z = \frac{\hat{p} - p}{\sqrt{\frac{p \cdot q}{n}}} \)
3. \( z = \frac{\bar{x} - \mu}{\frac{\sigma}{\sqrt{n}}} \) *(This option is selected)*
4. \( z = \frac{(\hat{p}_1 - \hat{p}_2) - (p_1 - p_2)}{\sqrt{\hat{p}(1 - \hat{p})(\frac{1}{n_1} + \frac{1}{n_2})}} \)
This content is structured to guide students in selecting the appropriate tool and formula for statistical calculations based on given conditions, particularly when the population standard deviation is provided.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Faa466c24-bbae-451a-a078-10dcd226e22a%2Fe76e918c-2725-483c-9a93-4b939a282163%2Fxeebbqf_processed.jpeg&w=3840&q=75)

1. **Round to the Nearest Whole Number:**
- \( \bar{x} \) (Sample Mean): ___
- \( \mu \) (Population Mean): ___
*(Note: Assume \( H_0 \) (the null hypothesis) is true until there is evidence against it.)*
2. **Round to Two Decimal Places:**
- \( \sigma \) (Standard Deviation): ___
3. **Sample Size:**
- \( n \) (Sample size): ___
4. **Round to Two Decimal Places:**
- \( z \) (Z-score): ___
**Step h**: Choose the option that best represents where the test value will be situated on the appropriate normal distribution curve.
- **Left-Tail Test**
