Respond to the following in a minimum of 175 words:Models help us describe and summarize relationships between variables. Understanding how process variables relate to each other helps businesses predict and improve performance. For example, a marketing manager might be interested in modeling the relationship between advertisement expenditures and sales revenues.Consider the dataset below and respond to the questions that follow:Advertisement ($'000) Sales ($'000)1068 44891026 5611767 3290885 41131156 48831146 5425892 4414938 5506769 3346677 36731184 65421009 5088Construct a scatter plot with this data.Do you observe a relationship between both variables?Use Excel to fit a linear regression line to the data. What is the fitted regression model? What is the slope? What does the slope tell us?Is the slope significant?What is the intercept? Is it meaningful?What is the value of the regression coefficient,r? What is the value of the coefficient of determination, r^2? What does r^2 tell us?Use the model to predict sales and the business spends $950,000 in advertisement. Does the model underestimate or overestimates ales?

However, recent studies have shown that earlier monitoring of risk factors such as blood pressure can be very beneficial (The Wall Street Journal, January 10, 2012). Having higher than normal blood pressure, a condition known as hypertension, is a major risk factor for heart disease. Suppose a large sample of individuals of various ages and gender was selected and that each individual’s blood pressure was measured to determine if they have hypertension. For the sample data, the following table shows the percentage of individuals with hypertension.a.Develop a side-by-side bar chart with age on the horizontal axis, the percentage of individuals with hypertension on the vertical axis, and side-by-side bars based on gender.b.What does the display you developed in part (a), indicate about hypertension and age?c.Comment on differences in gender.AgeMaleFemale20 - 3411.0%9.0%35 – 4424.0%19.0%45 – 5439.0%37.0%55 – 6457.0%56.0%65 – 7462.0%64.0%75 +73.3%79.0%3.The department of transportation’s study on driving speed and miles per gallon for midsize automobiles resulted in the data below.a.Plot the speed and miles per gallon using a scatter plot with speed on the horizontal axis.b.Compute the sample mean and standard deviation for each variable.c.Compute the sample correlation coefficient.

The following cross-tabulation shows the number of households (1,000s) and the household income by the highest of level of education for the head of the household (U.S. Census Bureau website, 2013). Only households in which the head has a high school diploma or more are included.a.Develop a joint probability tableb.What is the probability of the head of one of these households having a master’s degree or more education?c.What is the probability of a household headed by someone with a high school diploma earning $100,000 or more?d.What is the probability of one of these households having an income below $25,000?e.What is the probability of a household headed by someone with a bachelor’s degree earning less than $25,000?f.Is household income independent of educational level?Highest Level of EducationHousehold IncomeUnder $25,000$25,000 to $49,999$50,000 to $99,999$100,000 and OverTOTALHigh School Graduate988099709441348232,773Bachelor’s Degree248441647666781722,131Master’s Degree6851205301940949003Doctoral Degree7916042210761737TOTAL13,12815,49920,54816,46965,644

Assess the appropriateness of using a simple random sample as the test’s sampling plan, discussion help
Review the important themes within the sub questions of each bullet point. The sub questions are designed to get you thinking about some of the important issues. Your response should provide a succinct synthesis of the key themes in a way that articulates a clear point, position, or conclusion supported by research. You are designing a direct marketing campaign for an online clothing retailer. As part of your design, you quantify the expected response rates by ethnic group. Your definition of the term “ethnicity” follows that of the U.S. Census Bureau (e.g., Hispanic, Asian, African American, etc.). You want to test your campaign using 1,000 randomly selected households, but you want your sample to mimic the US population in terms of the proportion of different ethnicities (e.g., if Hispanics constitute about 12 percent of the US population, 12 percent of your sample should be Hispanic). Assess the appropriateness of using a simple random sample as the test’s sampling plan.Evaluate other potential sampling plans, and describe why such other sampling plans might be more or less appropriate than using a simple random sample. Support your discussion with relevant examples, research, and rationale. Your posting should be the equivalent of 1 to 2 single-spaced pages 500 words in length.
