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.

Level of Significance 0.05

Based on the sample data, can you conclude that the mean price of a hotel room in Atlanta is lower than one 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. ____________________

Question 1: [5 Points]

For each of the following systems, choose a suitable architecture style, then justify your choice.

1. An aquarium contains exotic tropical fish. The fish require the water temperature to be between 20 C - 23 C otherwise the fish will get sick. An automated heater is used to maintain the water temperature within that range. It turns on when the water gets too cold. It turns off when the water reaches the desired temperature.

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.

"Savor"BlackBeans: 71, 80, 81, 77, 82, 72, 79, 85, 78, 76

"Praise"Seitan: 83, 79, 77, 85, 80, 86, 78, 84, 83, 80

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.***

A company asks you to design a controller for a basketball machine that will indicate that a player has won a game if they get a total of 3 points. There are two sensors in this machine. One in the backboard and on the inside of the orange rim. If a player shoots a shot and the ball hits the backboard and the ball goes through the rim, then the play will gain 1 point. If the player shoots the ball and it doesn't hit the backboard and the ball just goes through the rim, then the play will gain 2 points. If the player hits the backboard and the ball does not go through the rim, then the player will lose 1 point. The total score can only go down to zero and cannot become negative. If the ball does not go through the rim or hit backboard, then it will count as a no shot and nothing will happen. Once the player scores three points, the game ends, and a light will indicate that the player has won.

Part A: Make a state table that describes each state in plain English and describe each binary value used.

Part B: Make a state diagram.

Park C: Make a k-map.

Part D: Make the synchronous machine schematic.

You can use either a Moore or Mealy machine and either a J-K Flip Flop or a D Flip Flop.

I was thinking about using 2-bit binary but then I got stuck so I switched to 3-bit binary and what I have looks good to me but now making the k-map is making me doubt what I have so here I am asking for help.
