1)      How many different things did you count? What were they? In what ways might computers be used to control different things in the supermarket?

A:  There are 6 different electrical thing in Mike’s day, and there are AC, car park barrier, freezer, parking sensors, public lights, automatic opening door.;

2)      Why is it useful to use computers rather than people to control things? What problems might there be if any of the computer system fall in the supermarket?

A: Because when computer is calculating is faster than when people are calculating. If the computer system is fall in the supermarket than it will cause 10 to 15 minutes to work. 

3)      Describe the inputs and outputs for the other devices that we have talked about so far. How do the super market doors and car park barriers know when to open? Identity other control systems that work automatically in this way.

A: The control system will detect things in a certain area. Therefore the door will open if things are in that area.

4)      What would happen if the instructions were wrong? These instructions assume that the car is in the right place. What would happen if the car were not there? How could they stop this happening?

A: The car will not work properly, because some parts of the car went wrong. So it will cause the car not to work properly. E.G. The brake cannot stop the car from moving, etc.

1)     How could Mussie and Elli find out whether older people do more for charity than younger people?

They can do street interview, chat online system (e.g. Facebook), asking teacher and classmates at school, interview old age home, etc.

2)     Why does Mussie think that these data prove him? Why might Ellie think that these data do not him right?

For Ellie answer is that the information might be not true.

For Mussie answer is that the data has shown him the acceptable answer.

3)     What question should they ask?

·           Who are you?

·           How often do you donate money to the charity?

·           What types of charity do you donate to?

·           How much money do you donate to the charity usually?

·           Do you do charity work?

– If yes: How long do you spend time doing in charity events?

4)     How many questionnaires should they hand out? Who do you think should fill in their questionnaire?

I think they should hand out 45 copies first, and if it went out within the first 3 to 4 days. I think the next time they reprint should be 53 copies. Also this questionnaires are every one (but not for the babies, because they will not understand a word if he/she receive the question sheet).

Q5: Which Software could Mussie and Ellie use to put answers into the computer? How can they check that the data are correct? How could they reduce the number of errors in the data? What problems might be if the data if typed incorrectly?

Answer: They could use Excel to put the answers in. They'll check the data before putting it onto the spreadsheet. They restrict the computer to themselves because if the data was typed incorrectly, they might go into the wrong conclusion.

Q6: What is the

best way

for Ellie and Mussie to present the results?

Answer: They can use a Pie Chart to show their results in percentage
