Answer:
The margin of error is<em> 0.22</em>
Step-by-step explanation:
Mathematically, the margin of error at the given confidence interval can be calculated using the formula below;
Margin of error = × s/√n
where is the t-value at the given confidence interval, s is the standard deviation and n is the sample size
= 1.96 (From t-distribution table)
s = 2.5 inches
n = 500
MOE = 1.96 × 2.5/
MOE = 1.96 × 2.5/22.36
MOE = 0.22
