Determine whether the data set is a population or a sample. Explain your reasoning. A survey of 500 spectators from a stadium with 42,000 spectators

In this problem, we're gonna make a scatter plot of the provided data. So in 1990 the population was 11,500. So going to be right about here in 1995 the population was about 12,000 100. So out there in 2000 the population was 12,700 so above the halfway point. Somewhere there, in 2005 the population was 13,000. So right about there. And in 2010 the population was 13,750. So 500 here, some shifty right there. And now what we have to do is answer the following question. If we wanted to know when the population would reach 15,000 with the answer involved interpellation or extrapolation. So the data provided 15,000 is not part of this data set. And therefore, in order to find in what year you would reach 15,000 you would need extrapolation. And if we connect the dots here just approximately, it looks to be that we reached a population of 15,000 near about 2021 or 2020 in that area. So the population 15,000 is reached in tow.

222 like X is equal to your after 19 nineties. So for 1990 X is equal to zero for 1995 exits fortified and so on. We saw this 0.0 in 11,500 which is here. Okay, so not all five points. So do these are country blood. Okay. Now, in order to predict when the population will take 15,000 dined dancer in rolls, Extra bonus in people's hero 15,000. Issue after Dundee 14,750 Duties or maximum deportable working. So for 15,000. Okay, because no, no range. So that is extrapolation. Okay, so here are our end points are 20 and want to survive, you know, and left. And point, that is cereal double when fire double zero. So explain why one is equal. Zero Don't let alone find evidence, you know. Jeez, Why intercept? Okay. On X to White, too. Did you quit this? 21 375 deal. Okay, now sloppiest given by, um, musical y two minus y one. Divided right. Extra minus X one. You're right. Dui's. I want to be sent by you. Minus Why one that is level by de Macedo Extra. That is 20 on X one, which is sealed. So where's slow? Please? Double oneto Want Why? Okay, My congressional Delaney's why is it? And next plus c you're See, they were waiting to set on. That is 11 by double zero on our slow these double oneto fight. So your question on the line buddies stumble into work by X loves 11,500 Okay, No. Take Wise's Orgel victim Calvin and sold for X. You're 15,000 is recording double. Want to quantify X? Who knows? Boland, find other zero Most subject this Now you heard about this? Will you vote side? So you're old X is equal 31 point double one. So your ex is three year after 90 90 Sold 1919 plus 31.1, which is a boardroom 2021.1 We are, which is approximate toe 2021. So in the year 2021 population would reach 15,000. Okay. Thank you

Okay, so this is our Western number. 222. For the following data, we need to go spend it so that X is equal to the number of year after 1990. So for their 90 90 take exit called, you know, for the your 1995 take X is equal to five and so on. Right for 200 the Rexes ical detent between Wendy and so on. Right? So for the excesses used to your and for the y axis use population, right? And our most morty zero in No. 1500 You all right? X is equal to do. And here y is equal 11,500. This is our first point. And so a little. Is there a scourge of God? No question is so went of operation will reach 15,000 Were dancing in annual interpolation or next level. Listen right So as you can see here. Range of twenties 11,502. 13,000 No older than 50 right? And as we can see here, 15,000 is not lies between this range. Right? So we can say answer would involve extrapolation, right? No, for Do you have a duty or everyone called him? We need to enter the X values and for all to call if we need to. Booty population. Really? Or we can say why. Really Right. So by racing enter, we have value over. That is ones your weight and the value of the ladies alone. 1005 130 right to a question of blindness. X plus be and you raise one, do away and your beauty's 11,000 Why 140 Marty, why is it called a 15,000 and sword for X of your one Do it takes is equal to 15,000 minus in 5 1030 Which is it going to before? Sound legal? No, direct by one. The right. Both sides. We're here blocks in millions of that, he started to 0.1 boot when we can say 32. Right? That is the authority to your after 1990. So that your ease 2022. Right, So in 2000 and 22 population will reach 15,000 right? Thank you.

For number 24. We need to get the midpoint of our frequencies. And so we take five plus 11. Divide by two. That's going to get us eight than the next man points going to be 15 20 to 29 33. Plus, we learned about about using here's 36 36 and then 40 plus four. Six is gonna be a midpoint of 43 so that our next test is to take their frequency times or midpoint for this next column. And then this other column is frequency Kind of. Points were to do that one day a 64 and eight times eight squared is going to get me 512 5 times 15 is gonna get me 75 than five times 15 square going to get me 11. 25 sometimes 20 Tuesday 1 54 7 times 22 squares only 33 88 One time she was 29 then one times 29 s weird is going to get me 8 41 one times 36 is 36 1 time. 36 Weird 12 96. Lastly, 3 40 29. And then three time 43 squared is 55 47. So then we do need a total up that first column f times MP. When we add all those we get 4 87 And then when we total up, this last column had up all those who should get 12,007 09 Okay, so then we're ready to our being. So our variance is s squared, and that's our numbers are frequency N is equal to 25. So we do 25 here. Times are bigger. Total 12,007 09 minus the 4 87 total squared divided by 25 times before the an minus 1 25 miles one. So then we're going to get that top part in bottom part figured out that's going to get us 80 and 556 on pop 25 24 600 and then divide. You should get approximate was aptly 1 34 my dukes. And then, in order to get hours in a deviation, we're gonna swear route that 1 34.26 So it's equally, um, and when we do that, around 11.6 is our final answer
