Census Bureau data shows that the mean household income in the area served by a shopping mall is $64,500 per year with the stand

Elenna [48]

Considering the situation described, the null hypothesis is given as follows:

$H_0: \mu = 64,000$ .

<h3>What are the hypothesis tested?</h3>

At the null hypothesis, it is tested if the <u>mean is the same as in the Census</u>, of $64,000, hence:

$H_0: \mu = 64,000$ .

At the alternative hypothesis, it is tested if the mean is different from the Census, hence:

$H_1: \mu \neq 64,000$ .

Likurg_2 [28]

$\bf \begin{cases}
f(x) = x^2 + 1\\\\
g(x) = 3x + 1
\end{cases}\quad 
\begin{cases}
f(1)=\boxed{1}^2+1\to &\boxed{?}\\\\
g(4)=3(\boxed{4})+1\to &\boxed{?}
