Question

**Study on Auditor Judgment**

Auditors must make judgments about various aspects of an audit based on direct experience, indirect experience, or a combination of both. In a study, auditors evaluated the frequency of errors in an audit. Their judgments were compared to actual results to determine accuracy. Lower scores indicate better judgment accuracy.

**Data Table:**

| | Direct | Indirect | Combination |
|-------------|--------|----------|-------------|
| **Scores** | 17.8 | 16.9 | 24.7 |
| | 18.6 | 21.2 | 23.6 |
| | 16.4 | 20.8 | 21.8 |
| | 18.0 | 19.1 | 27.2 |
| | 20.2 | 23.3 | 27.7 |
| | 15.3 | 20.5 | 24.9 |
| | 13.2 | 21.9 | 24.8 |

**ANOVA Table:**

\[
\begin{array}{|c|c|c|c|c|c|}
\hline
\text{Source of Variation} & \text{Sum of Squares (to 2 decimals)} & \text{Degrees of Freedom} & \text{Mean Square (to 2 decimals)} & F (to 2 decimals) & p-\text{value (to 2 decimals)} \\
\hline
\text{Treatments} & & & & & \\
\hline
\text{Error} & & & & & \\
\hline
\text{Total} & & & & & \\
\hline
\end{array}
\]

Use $\alpha = 0.05$ to test if the judgment basis affects the judgment's quality.

Many people now turn to the internet to get information on health-related topics. A research article used Flesch reading ease scores (a measure of reading difficulty based on factors such as sentence length and number of syllables in the words used) to score pages on Wikipedia and on WebMD. Higher Flesch scores correspond to more difficult reading levels. The paper reported that for a representative sample of health-related pages on Wikipedia, the mean Flesch score was 26.9 and the standard deviation of the Flesch scores was 14.9. For a representative sample of pages from WebMD, the mean score was 43.5 and the standard deviation was 19.2. Suppose that these means and standard deviations were based on samples of 40 pages from each site. Is there convincing evidence that the mean reading level for health-related pages differs for Wikipedia and WebMD? Test the relevant hypotheses using a significance level of 0.05. (Use μ₁ for Wikipedia and μ₂ for WebMD.) USE SALT State the appropriate…
A middle school wanted to examine if students' sense of school belongingness increased after participating in a two-week after-school program. Thirty students were selected to participate in the after-school program. Prior to completing the program, students completed a measure of school belonging. At the end of the two-week program, students completed another measure of school belongingness. Students' scores before and after the program were then compared. What is the IV?

You are a public health researcher. You want to see if the average age that a person starts smoking has changed over time. Smokers are recruited to answer a survey that asked at what age they started smoking. You divided participants into two groups, one is participants under the age of 30 and the second for participants over the age of 30. The average age for the two groups were compared. Which statistical test would be best to determine if there is a significant different in starting age between the two groups.
You may need to use the appropriate appendix table or technology to answer this question. According to the Vivino website, suppose the mean price for a bottle of red wine that scores 4.0 or higher on the Vivino Rating System is $32.48. A New England-based lifestyle magazine wants to determine if red wines of the same quality are less expensive in Providence, and it has collected prices for 65 randomly selected red wines of similar quality from wine stores throughout Providence. The mean and standard deviation for this sample are $30.15 and $12, respectively. (a) Develop appropriate hypotheses for a test to determine whether the sample data support the conclusion that the mean price in Providence for a bottle of red wine that scores 4.0 or higher on the Vivino Rating System is less than the population mean of $32.48. (Enter != for ≠ as needed.) H0: Ha: (b) Using the sample from the 65 bottles, what is the test statistic? (Round your answer to three decimal…

A psychologist wanted to know if students in her class were more likely to cheat if they were low achievers. She divided her 60 students into three groups (low, middle, and high) based on their mean exam score on the previous three tests. She then asked them to rate how likely they were to cheat on an exam if the opportunity presented itself with a very limited chance for consequences. The students rated their desire to cheat on a scale ranging from 1-100, with lower numbers indicating less desire to cheat. Before opening the data, what would you hypothesize about this research question? Open the data set. Before running any statistical analyses, glance through the data. Do you think that your hypothesis will be supported? Conduct descriptive analyses and report them here. Conduct a one-way ANOVA.

A statistical program is recommended. The Condé Nast Traveler Gold List provides ratings for the top 20 small cruise ships. The data shown below are the scores each ship received based upon the results from Condé Nast Traveler's Annual Readers' Choice Survey. Each score represents the percentage of respondents who rated a ship as excellent or very good on several criteria, including Shore Excursions and Food/Dining. An overall score was also reported and used to rank the ships. The highest ranked ship, the Seabourn Odyssey, has an overall score of 94.4, the highest component of which is 97.8 for Food/Dining.

The accompanying table gives amounts of arsenic in samples of brown rice from three different states. The amounts are in micrograms of arsenic and all samples have the same serving size. The data are from the Food and Drug Administration. Use a 0.05 significance level to test the claim that the three samples are from populations with the same mean. Do the amounts of arsenic appear to be different in the different states? Given that the amounts of arsenic in the samples from Texas have the highest mean, can we conclude that brown rice from Texas poses the greatest health problem? Click the icon to view the data.

Use the following information to answer the question. Many couples believe that it is getting too expensive to host an "average" wedding in the United States. According to the website www.costofwedding.com,theaveragecostofaweddingintheU.S.in 2009 was $24,066. Recently, in a random sample of 40 weddings in the U.S. it was found that the average cost of a wedding was $23,224, with a standard deviation of $2,903. On the basis of this, a 9 5% confidence interval for the mean cost of weddings in the U.S. is $22,296 to $24,152. Does the confidence interval provide evidence that the mean cost of a wedding has decreased? Explain your reasoning.
