a.
$370.60; higher than the national average
b.
$292.17; higher than the national average
c.
$38.35; lower than the national average
d.
$308.83; higher than the national average

Answer 1

Average = (288 + 310 + 325 + 294 + 293 + 343) / 6 = 1853 / 6 = 308.83 (≈$308.83).
This is higher than the national average ($270.48) by $308.83 − $270.48 = $38.35.

Answer: d.
