The breaking strengths of cables produced by a certain manufacturer have a standard deviation of 92 pounds. A random sample of 90 newly manufactured cables has a mean breaking strength of 1700 pounds. Based on this sample, find a 95% confidence interval for the true mean breaking strength of all cables produced by this manufacturer. Then give its lower limit and upper limit. Carry your intermediate computations to at least three decimal places. Round your answers to one decimal place
Answer:
To find the 95% confidence interval for the true mean breaking strength of all cables produced by the manufacturer, we can use the formula:
Confidence Interval = Sample Mean ± (Critical Value * Standard Error)
First, let's calculate the standard error, which is the standard deviation divided by the square root of the sample size:
Standard Error = Standard Deviation / √(Sample Size)
= 92 / √(90)
≈ 9.685
Next, we need to determine the critical value corresponding to a 95% confidence level. Since the sample size is large (n > 30), we can use the z-table. The z-value for a 95% confidence level is approximately 1.96.
Now we can calculate the confidence interval:
Confidence Interval = Sample Mean ± (Critical Value * Standard Error)
= 1700 ± (1.96 * 9.685)
Lower Limit = 1700 - (1.96 * 9.685)
≈ 1679.69
Upper Limit = 1700 + (1.96 * 9.685)
≈ 1720.31
Therefore, the 95% confidence interval for the true mean breaking strength of all cables produced by this manufacturer is approximately (1679.7, 1720.3). The lower limit is 1679.7 pounds, and the upper limit is 1720.3 pounds.

O Great Compromise
O Due Process
O Popular Sovereignty
Answer: Popular Sovereignty
Explanation:
Answer:
\(\boxed {\boxed {\sf Popular \ sovereignty}}\)
Explanation:
Let's define each answer choice.
Great Compromise
This was a combination of the New Jersey Plan and Virginia Plan. The NJ plan called for one Congress house with equal representation. The VA Plan vouched for two houses in Congress with representation based on population. The compromise resulted in present-day Congress with equal representation in the Senate and population-proportionate representation in the House of Representatives.Due Process
Citizens must be treated justly and all of their rights must be observed and followed in legal proceedings.Popular Sovereignty
The idea that people ("consent of the governed") provide the power for a government.Based on our definitions above, we can assume that the "idea that declares people have the power in creation of government" is popular sovereignty.

Review of peter Sykes please.
Answer:
PETER SYKES is good book which you can definitely refer but you can not entirely rely on this book for your theory as theory in this book containing JEE syllabus is so brief that is hard to understand at once. I personally referred this book rather than SOLOMONS, because I was already in comfort with the organic chemistry and my class notes was enough for me. But our teacher asked us to read this book in general to get better insight on the topics. But if you are not comfortable at the basics itself than this book is not for you definitely, you can use another books like paula yurkaniis bruce, solomons etc. And for questions both MS chouhan and Akshay choudhary is good.

Original Slope: ?
Parallel Slope: ?
The line that is drawn parallel to the given line is the green line shown in the image below.
Original slope = 1/2
Parallel slope = 1/2.
How to Find the Slope of a Line?The slope can be calculated as, m = change in y / change in x = rise / run.
The slope (m) of the given line = rise/run = 1/2
Parallel line have the same slope, therefore, the line that would be drawn parallel to the given line will have a slope, m = 1/2.
The equation of the original line is: y = 1/2x - 3. Thus, the line that is parallel to y = 1/2x - 3 that is displayed in the given graph will have an equation that has the same slope but different y-intercept, which can be: y = 1/2x + 2.
The two lines are shown in the image below, where red line is the original line and green line is the parallel line that is drawn.
