Question

4. Select a random sample of data from your dataset. The data should have a minimum of 30 cases, but not more than 200 cases. (Hint: You can use the “random” function in either Excel or SPSS to generate a random sample from your dataset.)

	Living arrangement
Sense of isolation	Housing development	Integrated Neighborhood	Totals
Low	80	30	110
High	20	120	140
Totals	100	150	250

Answer 1

		Housing development	Integrated Neighborhood	Total
Low	Observed	80	30	110
	Expected	44.00	66.00	110.00
	O - E	36.00	-36.00	0.00
	(O - E)² / E	29.45	19.64	49.09
High	Observed	20	120	140
	Expected	56.00	84.00	140.00
	O - E	-36.00	36.00	0.00
	(O - E)² / E	23.14	15.43	38.57
Total	Observed	100	150	250
	Expected	100.00	150.00	250.00
	O - E	0.00	0.00	0.00
	(O - E)² / E	52.60	35.06	87.66
		87.66	chi-square
		1	df
		7.76E-21	p-value

The p-value is 0.0000.

Since the p-value (0.0000) is less than the significance level (0.05), we can reject the null hypothesis.
