Considering the situation described, the null hypothesis is given as follows:
[tex]H_0: \mu = 64,000[/tex].
At the null hypothesis, it is tested if the mean is the same as in the Census, of $64,000, hence:
[tex]H_0: \mu = 64,000[/tex].
At the alternative hypothesis, it is tested if the mean is different from the Census, hence:
[tex]H_1: \mu \neq 64,000[/tex].
