Do men and women invest similarly

1.Do men and women invest similarly? Construct confidence intervals for the differences in mean Capital Gains, Capital Losses and Dividends.

2. Do those who file singly and jointly have same investment results as those who file jointly??

Select, perform and interpret an appropriate test

Recommend a chi-square test of independence to determine if investment level is independent of gender.

Capital Gains	Zero	Greater than zero	total
Joint	531	172	703
Single	210	87	297
	741	259	1000

Capital Losses	Zero	Greater than zero	total
Joint	621	82	703
Single	233	64	297
	854	146	1000

Dividends	Zero	Greater than zero	total
Joint	162	541	703
Single	118	179	297
	280	720	1000

In order to provide a chi-square test – the null and alternate hypothesis must be provided; additionally the chi square calculations need to be demonstrated; the decision regarding the null hypothesis must be presented – including rationale.

3.Compare differences in investment results for the other demographic variables, being careful to check assumptions and conditions.

Make suitable displays. Are there outliers to be concerned with?? Discuss.

Recommend a chi-square test of independence to determine if investment level is independent of each demographic variable; this is an example of the “some college” / “no college” demographic.

Capital Gains	Zero	Greater than zero	total
Some college	556	174	730
No college	187	83	270
	743	259	1000

Capital Losses	Zero	Greater than zero	total
Some college	620	110	730
No college	235	35	270
	855	145	1000

Dividends	Zero	Greater than zero	total
Some college	178	552	730
No college	103	167	270
	281	719
