The Tippie College of Business obtained the following results on the salaries of a recent graduating class: ### Salary Analysis for Finance and Business Analytics MajorsThe Tippie College of Business collected the following data on the salaries of a recent graduating class:- **Finance Majors:** - Sample size ($ n_1 $) = 130 - Average salary ($ \bar{x}_1 $) = $48,877 - Standard deviation ($ s_1 $) = $16,000- **Business Analytics Majors:** - Sample size ($ n_2 $) = 25 - Average salary ($ \bar{x}_2 $) = $55,157 - Standard deviation ($ s_2 $) = $12,000#### Hypothesis Formulationa. Formulate hypotheses with the significance level $ \alpha = 0.05 $:- Null Hypothesis ($ H_0 $): $ \mu_1 - \mu_2 \geq 0 $- Alternative Hypothesis ($ H_a $): $ \mu_1 - \mu_2 < 0 $#### Statistical Analysisb. Calculate the test statistic value, ensuring negative values are correctly noted. Round your answer to 2 decimal places.c. Determine the p-value:- Calculate degrees of freedom ($ d.f $), rounding down to the nearest whole number.- Calculate the p-value, rounding to 3 decimal places.#### Conclusiond. Analyze the results and conclude whether:- You conclude - You cannot conclude ...that the salaries of Finance majors are lower than those of Business Analytics majors.Please use the dropdown menu to select your conclusion based on the statistical analysis.

a. Assume that the observations are independent. Further, the population variances are not…

A mayor running for re-election claims that during his term, average municipal taxes have fallen by $225. A conscientious statistician wants to test this claim. She surveys 37 of her neighbors and finds that their taxes decreased (in dollars) as follows: 239, 231, 221, 213, 237, 213, 225, 240, 238, 217, 226, 221, 189, 189, 222, 219, 219, 226, 209, 225, 243, 223, 248, 258, 221, 234, 267, 225, 225, 217, 215, 236, 245, 241, 256, 226, 220 The statistician assumes a population standard deviation of $14.

The Wall Street Journal's Shareholder Scoreboard tracks the performance of 1,000 major U.S. companies. The performance of each company is rated based on the annual total return, including stock price changes and the re investment of dividends. Ratings are assigned by dividing all 1,000 companies into five groups from A (top 20%) , B (next 20%), to E (bottom 20%). Shown here are the one- year ratings for a sample of 60 of the largest companies.

Twenty-nine college students, identified as having a positive attitude about Mitt Romney as compared to Barack Obama in the 2012 presidential election, were asked to rate how trustworthy the face of Mitt Romney appeared, as represented in their mental image of Mitt Romney’s face. Ratings were on a scale of 0 to 7, with 0 being “not at all trustworthy” and 7 being “extremely trustworthy.” Here are the 29 ratings: 2.6 3.2 3.7 3.3 3.4 3.6 3.7 3.8 3.9 4.1 4.2 4.9 5.7 4.2 3.9 3.2 4.5 5.0 5.0 4.6 4.6 3.9 3.9 5.3 2.8 2.6 3.0 3.3 3.7 a 95% confidence interval for the mean rating. Is there significant evidence at the 5% level that the mean rating is greater than 3.5 (a neutral rating)?
A local health department believes that a store is merchandising its cereal aisle in a way that puts sugary cereal brands at eye level for children. The store claims that it is not considering sugar content and is stocking the shelves based on other factors.

At an assembly plant, workers assemble parts for a piece of farm equipment. The supervisor conducted an experiment to compare the effectiveness of three assembly methods, A, B, and C. Eighteen employees were randomly assigned, six employees each, to one of the three methods. After completing their training, each person was asked to assemble five pieces of equipment using his or her training method. The average time to complete the assembly of all five pieces of equipment was recorded. (a) What type of study design is used? O independent groups design O repeated measures design O matched pairs design O randomized block design What are the experimental units in this study? O the 18 employees O the five pieces of equipment to be assembled O the three assembly methods O the average time to assemble five pieces of equipment (b) What are the treatments?
