![**Normal Distribution Problem:**
Assume that the readings at freezing on a batch of thermometers are normally distributed with a mean of 0°C and a standard deviation of 1.00°C. A single thermometer is randomly selected and tested. Find the probability of obtaining a reading between -3.027°C and -1.553°C.
\[ P(-3.027 < Z < -1.553) = \]
*Interactive Component:*
- There is a text box provided for inputting the calculated probability.
- A "Check Answer" button is included for submitting the response.
**Instructions for Solving:**
1. **Understand the Distribution**:
- Mean (\(\mu\)) = 0°C
- Standard Deviation (\(\sigma\)) = 1.00°C
2. **Z-Score Calculation**:
- Use the Z-score formula for a standard normal distribution.
3. **Finding Probability**:
- Use standard normal distribution tables or a calculator to find the probability between the given Z-scores of -3.027 and -1.553.
4. **Input and Verify**:
- Insert the calculated probability into the provided text box and click "Check Answer" to verify.
