Answer:
D. 6
Step-by-step explanation:
Here we are given that a sample of 256 was taken from a population with a standard deviation of 96 centimeters i.e.
= 96 and n = 256.
And we have to calculate the margin of error for a 68% confidence interval.
Firstly from z score% table we observe that at 32% level of significance the z score critical value is given by 0.99744 .
<em>And Margin of error formula is given by ;</em>
*
= 0.99744 *
= 5.98
Approximately, we get Margin of error = 6.
Step-by-step explanation:

The equation in point slope form is y-1 = 1/4(x - 12)
<h3>Equation of a line</h3>
The formula for calculating the equation of a line is expressed as;
y = mx + b
m is the slope
b is the intercept
Slope = 1+3/12+4
Slope = 4/16
Slope = 1/4
For the intercept
1 = 1/4(12) + b
b = 1 - 3
b = -2
Hence the equation in point slope form is y-1 = 1/4(x - 12)
