Answer:
b. There is no difference between p1 and p2.
Step-by-step explanation:
Given that a 90% confidence interval for the difference of proportions contains some positive and some negative values
i.e. confidence interval lower bound is negative and upper bound is positive
This confirms that 0 is contained in the confidence interval for difference of proporitons at 90%
Hence for the hypotheses
we find that 0 is inside the confidence interval
This implies null hypothesis is accepted
Hence we conclude that there is no difference
b. There is no difference between p1 and p2.
The perimeter of a square is 4 times the length of its side. Therefore, the answer to this problem is 4x+3.

Answer:
- parallel: y = 4x -6
- perpendicular: y = -1/4x +27/4
Step-by-step explanation:
If we want the new line to be written in slope-intercept form, we need to find the new value of the y-intercept. The equation of the line is ...
y = mx +b . . . . . . . for slope m and y-intercept b
Solving for b gives ...
b = y -mx . . . . . . . subtract mx from both sides.
The values of x and y come from the point we want the line to pass through. The value of m will be the same for the parallel line as for the given line: 4. For the perpendicular line, it will be the opposite reciprocal of this: -1/4.
<u>Parallel line</u>
b = 6 -4(3) = 6 -12 = -6
y = 4x -6
Perpendicular line
b = 6 -(-1/4)(3) = 6 +3/4 = 27/4
y = -1/4x +27/4
