The error bound, also known as the margin of error, can be calculated from the confidence interval. Given the confidence interval $(95.25, 98.75)$, the error bound is the difference between the upper limit and the lower limit divided by 2.

Here's the step-by-step calculation:

1. Identify the lower limit and upper limit of the confidence interval:

   • Lower limit ($L$): 95.25
   • Upper limit ($U$): 98.75

2. Calculate the margin of error (E): $E = \frac{U - L}{2}$

Substituting the values:

= \frac{3.50}{2} = 1.75$$ Therefore, the error bound is $$1.75$$. Would you like any additional details or explanations? Here are 8 related questions: 1.
