Answer:
The MOE for 80% confidence interval for <em>μ </em>is 5.59.
Step-by-step explanation:
The random variable <em>X</em> is defined as the number of square feet per house.
The random variable <em>X</em> is Normally distributed with mean <em>μ</em> and standard deviation <em>σ</em> = 137.
The margin of error for a (1 - <em>α</em>) % confidence interval for population mean is:
Given:
<em>n</em> = 19
<em>σ </em>= 137
Compute MOE for 80% confidence interval for <em>μ </em>as follows:
Thus, the MOE for 80% confidence interval for <em>μ </em>is 5.59.
