### Educational Content on Survey Margin of ErrorIn a Morning Consult/Politico poll conducted in July 2020 with 1,997 registered voters, participants were asked if they believed the United States was headed in the "Right Direction" or on the "Wrong Track." The results showed that 74.9% felt things were on the wrong track, while 25.1% believed it was the right direction. The following content explains how to calculate and interpret the margin of error for such polls.---#### a) Calculating the Margin of ErrorThe margin of error (ME) for the proportion of all U.S. adults who believe things are on the wrong track was determined for a 99% confidence level:- **Margin of Error (ME) = 0.025**The calculation involved expressing the result to three decimal places as needed.---#### b) Interpreting the Margin of ErrorTo understand what this margin of error implies, consider the choices below. Select the appropriate meaning and complete the statement by filling in the answer box.- **A.** One is 99% confident that the observed proportion of adults that responded "Wrong Track" is within \[\_\_\_\] of the sample proportion. - **B.** The probability that any given adult surveyed from the population will respond "Wrong Track" is \[\_\_\_\]. - **C.** One is 99% confident that the observed proportion of adults that responded "Wrong Track" is within \[\_\_\_\] of the population proportion. - **D.** The probability that any given adult surveyed from the sample responded "Wrong Track" is \[\_\_\_\].When selecting the option, remember that the margin of error indicates the range within which the true population proportion is expected to fall, given the results from the sample.---This detailed explanation provides clarity on how statistical margins of error work in surveys and the level of confidence in interpreting such results.

It is given that in part (a), the margin of error ME = 0.025.

The governor of a state wanted to assess the public education system of the state. She instructed a group of researchers to create a test to assess the knowledge of every high school senior in the state. The researchers administered the tests and found that the average score was 74 points out of 100, with a standard deviation of 20 points. Complete parts (a) through (c) below. a. Identify the population and variable. Choose the correct population below. A. The population is the group of all high school seniors in the state. O B. The population is the group of every state's governor. O C. The population is the group of all high school teachers in the state. O D. The population is the group of all high school students in the state. Choose the correct variable below. O A. The variable is the number of high school seniors. O B. The variable is the test length.
