Case 2: Emily, an attractive 23-year-old secretary works for Cover-the-Earth Enterprises, a regional sales company employing over 200 employees. In late 2017, Emily is reassigned to work for Dan, a 60-year-old district sales manager. Dan often makes joking remarks to Emily about meeting after work at the Empty Arms Hotel in order to "get to know each other a little better." Emily is amused and laughs at Dan's suggestive remarks, retorting that he is much too old for that nonsense, or that "even if I did agree, you'd probably die of embarrassment or a massive heart attack."

Dan always laughs at Emily's witty retorts. Dan and Emily never meet after work, but often tease each other and engage in this form of repartee in the work area.

  1. The research around Leona’s Tacos has created quite a buzz and business is great. Leona is planning on expanding her menu and she’s going to start with a new taco filling. She is considering her own black bean mix “Savor” and Hadey’s famous braise of seitan “Praise”. She naturally performs a blind taste test with 20 randomly selected judges from Avocado Park. Each judge is randomly served a taco filled with either “Savor” or “Praise” and asked to assess the experience using a rubric that results in a score from 0-100. Leona’s findings can be found in the data below questions
    1. Identify the populations of interest.
    2. Identify the variable of interest.
    3. What type of variable is being studied here?
    4. What would be a suitable parameter for determining if the taco filling receive different scores?
    5. Write a null hypothesis for Leona’s study.
    6. Write an alternative hypothesis for Leona’s study.
    7. Leona decides to use a significance level of 0.05. What conditions must be met to test the hypothesis in part e?
    8. Calculate a P-Value for your null hypothesis from part e and make a decision about the null hypothesis based on this P-Value and the significance level stated in part g.
    9. Summarize your decision from part h.

Suppose that you are responsible for making arrangements for a business convention and that you have been charged with choosing a city for the convention that has the least expensive rooms. You have narrowed your choices to Atlanta and Houston. The table containing samples of prices for rooms in Atlanta and Houston is provided in the Excel Online file below. Construct a spreadsheet to answer the following questions. Because considerable historical data on the prices of rooms in both cities are available, the population standard deviations for the prices can be assumed to be $19.88 in Atlanta and $27.2 in Houston.

An important part of employee compensation is a benefits package, which might include health insurance, life insurance, child care, vacation days, retirement plan, parental leave, bonuses, etc. Suppose you want to conduct a survey of benefits packages available in private businesses in Hawaii. You want a sample size of 100.

Some sampling techniques are described below. Categorize each technique as simple random sample, stratified sample, systematic sample, cluster sample, or convenience sample. Put your answer in the blank.

a. Assign each business in the Island Business Directory a number, and then use a random number table to select the businesses to be included in the sample. __________________________

b. Use postal ZIP Codes to divide the state into regions. Pick a random sample of 10 ZIP Code areas and then include all the businesses in each selected ZIP Code area. ________________________

c. Send a team of five research assistants to Bishop Street in downtown Honolulu. Let each assistant select a block or building and interview an employee from each business found. Each researcher can have the rest of the day off after getting responses from 20 different businesses. _____________________

d. Use the Island Business Directory. Number all the businesses. Select a starting place at random, and then use every 50th business listed until you have 100 businesses. _____________________

e. Group the businesses according to type: medical, shipping, retail, manufacturing, financial, construction, restaurant, hotel, tourism, other. Then select a random sample of businesses from each business type. ____________________

Recording Observations Unobtrusively record observations in a public place of your choice for at least thirty minutes or more. The place must have at least ten people to observe. Since you are playing the role of an unobtrusive investigator, you must not disturb the people and must be positioned so that the people will not really take notice of you. You should watch people and focus on behaviors. The behaviors might be ordinary or interesting. You might even choose to look at behaviors related to a theme, such as how people relax or you can look at dyadic interactions. No matter what you choose to observe, you should describe what you witness. Record the observations in your notebook in a 1- to 2-page Microsoft Word document. The observations should not be conducted with any specific notions or theories. Type and submit your notes, which should be at least 500 words. Include the date of the observation, the time, and the setting. Along with your observation notes, include five specific study ideas that come to mind because of your observations. For example: After observing mothers and children in the park, I would like to investigate whether mothers with multiple children allow the children to venture further away from them as compared to mothers with one child. You must also state hypotheses for at least two of your study ideas. For example, you might hypothesize mothers with only one child will keep their child closer than mothers with multiple children. *** Please help with my homework I am struggling with. Thank you.***
