Answer:
[0.4979, 0.5479]
Step-by-step explanation:
-We first determine the sample proportion:
-The confidence intervals of a sample proportion is calculated using the formula:
#We substitute for the sample proportion and z value to get the Confidence interval:
Hence, the 90% confidence intervals is [0.4979,0.5479]
<em><u>Solution:</u></em>
Given that,
We have to find the equation in slope-intercept form for the line that passes through the point (-8, 3) and is parallel to the line -5x + 4y = 8
<em><u>The equation of line in slope intercept form is given as:</u></em>
y = mx + c
Where "m" is the slope of line
From given,
-5x + 4y = 8
Rearrange to slope intercept form
4y = 5x + 8
On comparing the above equation with slope intercept form,
We know that, slopes of parallel lines are equal
Therefore, slope of line parallel to the line -5x + 4y = 8 is:
Substitute c = 13 and m = 5/4 in eqn 1
Thus the equation of line in slope intercept form is found
