Answer 1

Descriptive Statistics
	Mean	Std. Deviation	N
Number of children	2.50	1.652	912
Children Living at Home	1.08	1.237	912

In this problem,

There are two sample's statistic value first is number of children and children living at home

We consider it's population parameter are as below

= Population mean of number of children

= Population mean of children living at Home

We write the null and alternative hypothesis for population parameter only

Using the above parameter, we write the null hypothesis are as below

Or

Or

We write the above null hypothesis in word are as

H₀ : There is no significant difference between two population means of number of children and children living at Home.

Summary :-

The null hypothesis is

1) Using the parameter

Or

2) Using the word

H₀ : There is no significant difference between two population means of number of children and children living at Home.
