To find the error interval for the number \( h \), which is rounded to two decimal places as \( 4.63 \), we need to determine the range of values that \( h \) could have been before rounding.

### Step-by-step solution:

1. **Lower Bound**: The smallest number that rounds up to 4.63 when rounded to 2 decimal places is halfway between 4.62 and 4.63. This is:
   \[
   4.625
   \]
   
2. **Upper Bound**: The largest number that rounds down to 4.63 when rounded to 2 decimal places is halfway between 4.63 and 4.64. This is:
   \[
   4.635
   \]
   However, since the upper bound is not included in the interval, we exclude it by writing \( h < 4.635 \).

### Final Error Interval:
The error interval for \( h \) is:
\[
4.625 \leq h < 4.635
\]

2. What is the concept of rounding in terms of significant figures?
3. Can you describe how rounding to different decimal places affects precision?
4. How do we calculate error intervals for numbers in scientific notation?
5. How is the concept of error intervals applied in real-world measurement scenarios?

**Tip**: When working with rounding and error intervals, always remember that the interval excludes the upper bound. This ensures the correct representation of the range of possible values.

A number, h, rounded to 2 decimal places is 4.63. Write down the error interval for h.
