The first two vertices are (-7,3) (-6,1)
Slope = (3 - 1)/(-7 + 6) = -2
Opposite side of the first two vertices so the lines are parallel.
Parallel lines, slope is the same so slope is also -2
Passing thru (-4,5)
y = mx + b
b = y - mx
b = 5 - (-2)(-4)
b = 1 - 8
b = -7
Equation:
y = -2x - 7

Answer:
The maximal margin of error associated with a 95% confidence interval for the true population mean is 2.238.
Step-by-step explanation:
We have given,
The sample size n=42
The sample mean 
The population standard deviation 
Let
be the level of significance = 0.05
Using the z-distribution table,
The critical value at 5% level of significance and two tailed z-distribution is

The value of margin of error is




The maximal margin of error associated with a 95% confidence interval for the true population mean is 2.238.
To find decimals out of fractions, you divide 13 and 20, which equals 0.65.
