Answer:
The margin of error for constructing a 95% confidence interval on the population mean income before taxes of all consumer units in the U.S is 1406.32.
Step-by-step explanation:
We are given that according to a survey of 500, the mean income before taxes of consumer units (i.e., households) in the U.S. was $60,533 with a standard error of 717.51.
Margin of error tells us that how much our sample mean value deviates from the true population value.
<u></u>
<u>Margin of error is calculated using the following formula;</u>
Margin of error =
where, = level of significance = 1 - confidence level
= 1 - 0.95 = 0.05 or 5%
Standard of Error = = 717.51
Now, the value of z at 2.5% level of significance () is given in the z table as 1.96, that means;
Margin of error =
= = 1406.32
Hence, the margin of error for constructing a 95% confidence interval on the population mean income before taxes of all consumer units in the U.S is 1406.32.

Answer:
66°{B}
Step-by-step explanation:
30°+57°+27°+x=180°
114°+x=180
x=180°-144°
66°
Answer:
56%
Step-by-step explanation:
Any number out of 100 is that number's percent.
If it's for say 0.1/100, its 0.1%.
The line with slope = 2 will be closer to the y-axis than the line with slope = 1/2
<h3>How to interpret the slopes?</h3>
The slopes are given as:
Slope = 2
Slope = 1/2
The greater the absolute value of the slope of a linear equation.
The closer the function is to the y-axis
This means that the line with slope = 2 will be closer to the y-axis than the line with slope = 1/2
