True mean = mean+/- Z*(SD/sqrt (n))
Where
Z = 1.96 at 95% confidence interval
Mean = 10.3 pounds
SD = standard deviation = 2.4 pounds
n= sample size = 37 packages
Substituting;
True mean range = 10.3+/- 1.96 * 2.4/Sqrt (37) =10.3+/- 0.77 = 9.53<mean<11.07
One yard is 0.0005 miles,
548 * 0.0005 = 0.274,
So the answer is 0.274 miles.
