Consider the following sample of houses collected from two neighbourhoods. It is presumed that both samples have the same population standard deviation.

Sample from area 1 of House prices in $1000s of dollars		Sample from area 2 of House prices in $1000s of dollars
677	695	806	1011	564		867	795	906	1011	514
1156	399	772	630	1114		1258	449	862	865	1104
1144	507	516	613	706		1547	457	546	723	602
877	1146	656	753	548		698	1148	1693	653	501
445	579	500	581	664		545	669	626	851	592
826	956	1146	680	886		816	1096	1156	860	908
746	1146	481	747	477		951	1256	594	760	505

• Based on the information - are these dependent or independent samples? Briefly explain.
• Using the 5 step hypothesis test procedure. Test at the ten percent level if the average value of houses in area two is greater than the average value in area 1.
• Would your results have changed if you had tested at a five percent level? Would it be ethical to go back and update your significance level if you wanted to prove one outcome over another? Briefly rationalize.
