**Analysis of Restaurant Meal Prices: ANOVA Study**The **Consumer Reports** Restaurant Customer Satisfaction Survey collected data from **148,599 visits** to full-service restaurant chains. The study focuses on the average meal price (excluding tips) by category: Italian, Seafood, and Steakhouse. Data was sampled from 24 restaurants, categorized equally into three groups of 8.### Data Overview- **Italian Restaurants ($)** - Prices: 11, 12, 13, 13, 19, 20, 18, 24 - **Seafood Restaurants ($)** - Prices: 15, 18, 13, 18, 21, 13, 17, 18 - **Steakhouse ($)** - Prices: 24, 18, 21, 25, 21, 31, 28, 30### PurposeTo determine if there is a significant difference in mean meal prices among the three restaurant types using an alpha level of **0.05**.### ANOVA Table Structure- **Source of Variation** - Treatments - Error - Total- **Columns** - Sum of Squares - Degrees of Freedom - Mean Square - F-statistic - p-value### Results Interpretation- The p-value is stated to be **less than 0.01**, indicating a significant difference in meal prices between the restaurant types.- **Conclusion**: Since the p-value is less than the alpha level of 0.05, we reject the null hypothesis. Therefore, not all treatment means are equal, indicating significant differences in meal prices across restaurant types.

In 1955, Life Magazine reported that a 25-year-old mother of three worked (on average) an 80 hour week. Recently, many groups have been studying whether or not the women's movement has, in fact, resulted in an increase in the average work week for women (combining employment and at-home work). Suppose a study was done to determine if the average work week has increased. 77 women were surveyed with the following results. The sample average was 83; the sample standard deviation was 1o. Does it appear that the average work week has increased for women at the 5% level? Note: If you are using a Student's t-distribution for the problem, you may assume that the underlying population is normally distributed. (In general, you must first prove that assumption, though.)

The Consumer Reports Restaurant Customer Satisfaction Survey is based upon 148,599 visits to full-service restaurant chains (Consumer Reports website). One of the variables in the study is meal price, the average amount paid per person for dinner and drinks, minus the tip. Suppose a reporter for the Sun Coast Times thought that it would be of interest to her readers to conduct a similar study for restaurants located on the Grand Strand section in Myrtle Beach, South Carolina. The reporter selected a sample of 8 seafood restaurants, 8 Italian restaurants, and 8 steakhouses. The following data show the meal prices ($) obtained for the 24 restaurants sampled. Use a = 0.05 to test whether there is a significant difference among the mean meal price for the three types of restaurants. Italian Seafood Steakhouse $ 10 $ 17 $ 26 $ 12 $ 17 $ 17 $ 16 $ 17 $ 21 $ 18 $ 28 $ 24 $ 17 $ 24 $ 23 $ 18 $ 13 $ 24 $ 17 $ 19 $ 26 $ 23 $ 18 $ 29 Source Sum of Squares Degrees Mean Square p -value (to whole…
The Federal Bureau of Investigation (FBI), as part of its internal security mission, serves as a database for all the reported crimes committed in the United States. One question that might be of interest is does having more police officers reduce the number of homicides?

Bank of America's Consumer Spending Survey collected data on annual credit card charges in seven different categories of expenditures: transportation, groceries, dining out, household expenses, home furnishings, apparel, and entertainment. Using data from a sample of 42 credit card accounts, assume that each account was used to identify the annual credit card charges for groceries (population 1) and the annual credit card charges for dining out (population 2). Using the difference data, the sample mean difference was d = $850 , and the sample standard deviation was sa = $1,123. a.

Two psychologists surveyed 587 children in grades 4, 5 and 6 in elementary schools in Michigan. They stratified their sample drawing roughly 1/3 from rural, 1/3 from suburban and 1/3 from urban schools. Among other questions they asked students whether their primary goal was to get good grades, to be popular, or to be good at sports. One question of interest was whether boys and girls at this age had similar goals.

Advertising aimed at teenagers tends to contain dance-beat music, adventure, and a fast pace rather than words. To test to see how teenagers respond to different types of commercials, 150 teenagers then watched a set of commercials with dance-beat music, adventure, and a fast pace. After the commercials, the teenagers were asked whether they would want to buy the product and 102 responded that they would buy the product. Another sample of 125 teenagers where shown a set of commercialscomprised primarily of words. After the commercials, the teenagers were asked whether they would buy the product and 60 responded that they would like to buy the product. Based on both samples, at the 5% level of significance, test the hypothesis that there is at least a 10% difference in the proportion of teenagers who would buy the product after watching the different types of commercials?
