You want to know whether the adults in your country think the ideal number of children to have is two, or higher or lower than that.

Define notation and state the null and alternative hypothesis for studying this.

For responses in the recent General Social Survey (GSS) to this question, "what do you think the ideal number of children to have?", software results produced the following:

Rest of mu = 2.0 vs. mu not = 2.0

Variable N (total number of cases) Mean Std. Dev. SE Mean T P-value

Children 1302 2.490 0.850 0.0236 20.80 0.0000

Report the test statistic value and show how it was obtained from the other values reported in the table.
