 * 1.2 Targeting an Audience**

// **Big Idea- Many important practical and mathematical applications involve comparing quantities of one ** //**// kind or another; it is important to know which method to use and how we should use them.

// A. Read the statements below about how Neilson students prefer to spend their evenings. Tell whether each statement accurately reports the results of the survey. Explain you answer. **1.6out of 10students prefer television to radio. Yes. because 60students prefer to watching televison out of 100. it means 100/60 which is 10/6=6out of 10 students. (ratio)

2.Students prefer radio to television by a ratio of 4 to 6. Yes. becuase 40 students are listen radio and 60 students are watching television. It means 40:60 which is 4 to 6. (ratio)

3.Students who prefer television outnumber those who prefer radio by 20. Yes, because 60 - 40 = 20. (difference)

4. Students who prefer television outnumber those who prefer radio by a ratio of 3 to 2. Yes, because when I simple it 60 to 40. the simplest ratio is 3 to 2. (ratio)

5. The number of students who prefer watching television is 1.5 times the number who prefer listening to radio. Yes, because 1.5 times of 40 is 60. (scaling)

6. 40% of the students prefer radio to television. Yes, because 40/100 is 40% of 100 students. (percent)

7. 3/5 of the students prefer television to radio. Yes, because 60/100 is equal to 3/5. (fraction)

I will choose statement 6 because it' doesn't compare the number of student that like radio with student that like TV and when I just hear 40% it's not bad.
 * B.If you were writing a paper to convince local merchants that they would reach more students by advertising on the radio than on television, which statement from above would you use? Why?**

I will choose statement 5 because it doesn't talk about how many people they surveyed, so it can seemed more than 100 and it sound like 1.5 time is really big.
 * C. Imagine that you are the advertising director for a television station in the town where Neilson is located. You have been asked to prepare a report for a meetin g between your ad department and a large local skateboard manufacturer. Which accurate statement from above would you use to try to convince the manufacturer to advertise on your station? Why?**

1. For each statement in part A on paage 7, write a similar statement about your class data.** 1. 6 out of 7 student prefer internet to television. 2. Student prefer tv to interent by a ration of 2:12 3. Students who prefer internet outnumber those who prefer tv by 10. 4. Students who prefer internet outnumber those who prefer tv by a ration of 1:6 5. The number of students who prefer watching internet is 6 times the number who prefer watching TV. 6. about 14% of students prefer tv to internet. 7. 6/7 of the students prefer internet to tv.
 * //__Follow- Up__//

Similar: Way that I present the data. I use ratio, fraction, decimal and percentage. Different: Numbers are different Survey size is smaller than Nelson's data. media is different.
 * 2. In what ways is your class data similar to the Neilson data? In what ways is your data different?**


 * 3. You may have heard people talk about atn interest group manipulation data to promeote thier cause. This doesn't mean they used incorrect data. but that they made careful decisions about which data to use and how to represent the data to support their cause. How could you manipulate you class data to presuade local merchants to advertise on radio rather than o televison?**

Don't mention the internet at all and compare television to radio. The number of students watching TV is 2 times bigger than students who listen to the radio. Have to put other things that is smaller than tv and compare with that.
