- Determine whether the following examples of data are quantitative or qualitative. Write "QUANTITATIVE" for quantitative and "QUALITATIVE" for qualitative. (without quotations) (a) The amount of bacteria on a piece of moldy bread. answer: (b) Your college GPA. answer: (c) The marital status of your coworkers. answer: (d) The occupation of your neighbors. answer: Note: You can earn partial credit on this problem.Some research questions are summarized below. For each situation, identify all variables and characterize them in terms of the level of measurement. Identify which variables are dependent and which are independent. a. Are male and female entrepreneurs different in terms of their business success (measured in how much money they made last year)? b. Do years in college change students’ perceptions of their resilience, grit, and perseverance (measured with scales)? c. How do international marriages (marriage between two people from different countries) change over time(measured in years)?Recent research indicates that the effectiveness of antidepressant medication is directly related to the severity of the depression (Khan, Brodhead, Kolts & Brown, 2005). Based on pretreatment depression scores, patients were divided into four groups based on their level of depression. After receiving the antidepressant medication, depression scores were measured again and the amount of improvement was recorded for each patient. The following data are similar to the results of the study. (see image #1) This is the summary table for the ANOVA test: S.S. d.f. M.S.

- GreenLawns provides a lawn fertilizer and weed control service. The company is adding a special aeration treatment as a low-cost extra service option, which it hopes will help attract new customers. Management is planning to promote this new service in two media: radio and direct-mail advertising. A media budget of $3,500 is available for this promotional campaign. Based on past experience in promoting its other services, GreenLawns obtained the following estimate of the relationship between sales and the amount spent on promotion in these two media. S = −2R2 − 10M2 − 8RM + 18R + 34M where S = total sales in thousands of dollars R = thousands of dollars spent on radio advertising M = thousands of dollars spent on direct-mail advertising. GreenLawns would like to develop a promotional strategy that will lead to maximum sales subject to the restriction provided by the media budget. (a) What is the value of sales (in dollars) if $2,500 is spent on radio advertising and $1,000 is…Some research situations are summarized below. For each situation, identify all variables.Then, for each variable, note the level of measurement AND whether it is an independent or dependent variable. a. A health researcher is interested in studying patient compliance (whether or not patients take the medicine their doctor prescribes). She surveys 800 diabetic patients, and finds compliance to be linked to patient age, education, gender, and socioeconomic status. b. A market researcher is hired by Target to see how customers buying habits have changed before and after COVID. The researcher studies how much each customer spent (in $s), how frequently they visited the website each month, how frequently they visited the store each month. They report that, since March, customers are spending less, visiting the website more frequently, and shopping in person less frequently.Some research situations are summarized below.
