Question: A group of young businesswomen wish to open a high fashion boutique in a vacant store, but only if the average income of households in the area is at least $25,000. A random sample of 15 households showed the following results.

$26,000 $24,500 $28,000 $24,000 $26,000 $27,000 $24,800 $25,200 $23,000 $27,000

$23,500 $26,200 $26,000 $24,000 $22,000

Use Wilcoxon’s Test to advise the group on whether or not they should locate the boutique in this store. Use a .05 level of significance.
