You are the VP, Advertising for “Yo’ Mama” brand, a fashion label that caters to the young, trendy crowd with an urban, hip-hop image. While your customer base has traditionally been largely African-American, you have recognized a tremendous influx of Hispanic consumers into your market. You are preparing for next week’s annual budget meetings and you have decided to recommend an Hispanic-focused advertising campaign if the average monthly per store sales to Hispanic customers are at least the same as the average monthly per store sales to African-American customers in a sample of typical stores (sales data given below). Using an alpha of .05 and the 5-step hypothesis testing process, what will you recommend? Hint: Think about how many data points you actually have.

- By 2019, nearly $1 out of every $5 spent in the U.S. economy is projected to go for health care. The bar graph shows the percentage of the U.S. gross domestic product going toward health care from 2007 through 2014, with a projection for 2019.By 2019, nearly $1 out of every $5 spent in the U.S. economy is projected to go for health care. The bar graph shows the percentage of the U.S. gross domestic product going toward health care from 2007 through 2014, with a projection for 2019. a. Use the function to determine the percentage of the U.S. gross domestic product that went toward health care in 2009. Round to the nearest tenth of a percent. Does this underestimate or overestimate the percentdisplayed by the graph? By how much? b. According to the model, when will 18.5% of the U.S. gross domestic product go toward health care? Round to the nearest year.arrow_forward3. Juwan and his friend Jamie are watching their favorite tech penny stocks in the stock market. The initial value of Jamie's stock was $4.00, while Juwan's stock's initial value was $0.00. Because of some incredible turns in the market this morning, the stocks are now increasing in value. Every time Juwan's stock rises by $4.00, Jamie's stock increases by $3.00. If these stock gains remain constant throughout the day, perform the following: a. Convert this scenario into two linear equations; show both the standard form and the slope-intercept form for both equations. b. Explain how you decided to label the axes. c. What are the realistic bounds for the domain and range of today's stock gains? Explain your answer.arrow_forwardRead the following scenario describing a research project, and then write a short criticism of this project. You should clearly identify at least four aspects of the project which you believe are incorrect or poor. These may relate to the research question, the experimental design, the analysis and reporting, and/or any ethical or academic misconduct issues. For each criticism which you identify, clearly describe the problem and state how it should have been addressed to improve the quality of the research. Question 15.A company providing on-line teaching software claims that students who are on-line students achieve better results on learning programming languages than on campus students. The company has developed a hypothesis based on this claim. The company chose one university to conduct research to test this hypothesis. It applied for research ethics clearance and at the same time included both on-line and oncampus students to participate in this experiment. At the end of…arrow_forward
- Two firms, Gene's Gloves and Wally's Wallets, have factories near a lake. Both firms use a chemical for tanning leather. Some of this chemical runs into the lake. Each year Gene's Gloves dumps 15,000 gallons and Wally's Wallets dumps 25,000 gallons into the lake. A new study has found that fish and other wildlife are negatively impacted by this chemical. The government has decided to cap the amount that the factories can dump into the river at 10,000 gallons per year. For an addition $1 per gallon, Wally's Wallets is able to substitute each gallon of harmful chemical for one gallon of a harmless alternative. Gene's Gloves needs to use the harmful but more effective chemical for production. It costs $3 per gallon to safely dispose of the harmful chemical. Assume that Gene's Gloves and Wally's Wallets maintain the same level of production under the new environmental restrictions. 1. Suppose the government gives each firm the right to dump 5,000 gallons each.

This decision was based on projections that streaming videos will replace DVDs in the future. In this problem, you will explore these projections. Numbers below are close to the correct values, but vary to allow more practice with this idea. Total DVD and Blu-ray disc sales in 2009 were $8.72 billion. For the purposes of this problem, you will combine DVD and Blue-ray disk sales into one category of DVD sales. A study by In-Stat predicted that "physical disc sales will decline by $4.7 billion by 2014," and that "streaming, on the other hand, should grow from its current $2.1 billion to $6.3 billion over the same time period (2009–2014)."12 What is the slope, including units, of the model for DVD sales?arrow_forward
- Harriet McNeil, proprietor of McNeil’s Auto Mall, believes that it is good business for her automobile dealership to have more customers on the lot than can be served, as she believes this creates an impression that demand for the automobiles on her lot is high. However, she also understands that if there are far more customers on the lot than can be served by her salespeople, her dealership may lose sales to customers who become frustrated and leave without making a purchase. Ms. McNeil is primarily concerned about the staffing of salespeople on her lot on Saturday mornings (8:00 a.m. to noon), which are the busiest time of the week for McNeil’s Auto Mall. On Saturday mornings, an average of 6.8 customers arrive per hour. The customers arrive randomly at a constant rate throughout the morning, and a salesperson spends an average of one hour with a customer. Ms. McNeil’s experience has led her to conclude that if there are two more customers on her lot than can be served at any time on…arrow_forwardYou are the marketing director for a company that manufactures bodybuilding supplements, and you are planning to run ads in Sports Illustrated and GQ Magazine.
