A national survey conducted in 2011 among a simple random sample of 1450 adults shows that 57% of Americans think the Civil War is still relevant to American politics and political life. (a) Conduct a hypothesis test to determine if these data provide strong evidence that the majority of the Americans think the Civil War is still relevant. Use a significance level of a = 0.08. Ho : prop = HA: prop> p-value: Based on this information, we may Reject the Null Hypothesis (b) Calculate a 99% confidence interval for the proportion of Americans who think the Civil War is still relevant.
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.

![A national survey conducted in 2011 among a simple random sample of 1450 adults shows that 57% of Americans think the Civil War is still relevant to American politics and political life.
(a) Conduct a hypothesis test to determine if these data provide strong evidence that the majority of the Americans think the Civil War is still relevant. Use a significance level of α = 0.08.
\[H_0: \text{prop} =\] [Dropdown]
\[H_A: \text{prop} >\] [Dropdown]
\[p\text{-value}: \quad \_\_\_\_\_\]
Based on this information, we may [Dropdown: Reject/Do Not Reject] the Null Hypothesis.
(b) Calculate a 99% confidence interval for the proportion of Americans who think the Civil War is still relevant.
\[( \_\_\_\_\_\ , \_\_\_\_\_\ )\]
In this text, there are placeholders for conducting a hypothesis test and calculating a confidence interval. The hypothesis might be structured around whether the proportion is greater than 0.5, indicating a majority. The p-value would help in deciding to reject or not reject the null hypothesis, and the confidence interval provides a range of values for the proportion.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F9ca41c16-4f8c-4ab4-a43c-8316ac02cc45%2F4aa0274f-7435-4211-b763-8755c52ee939%2Fwldqt7i_processed.png&w=3840&q=75)
