Repeat question 1 for waves of wavelength $1 \mathrm{mm}$ approaching an aperture of size $20 \mathrm{cm}$.

And this problem we're dividing 11,304 divided by 12. So I've been an estimate first. So what we have is about 11,000 divided by about 10 will say, And that's gonna be whenever we divide by 10. We could think of a couple of ways to think about it. We can really of what it means is we're really moving the decimal over one place. Or we could just cross off the 10 So answer is gonna be about 1100. So Ah, let's see if that happens. We're gonna go ahead and just do this as usual, Um, and put them in the proper place. So we see that 12 goes into ah, 113. I know that 12 times nine is 108 of the closest 230 I'm gonna get. So I'm gonna go ahead and say, Put nine up here and that's gonna be one of eight and 13 minus eight. It's five. Bring down zero focus into 54 times. That's 48. There's two left over. Remember, you're subtracting there and then bring down before, and I know that that's too. So 12 times two is 24 semi final answer is 942 which is, um, it's not really I got as close as it wasn't. We're adding or subtracting and estimated, but because multiplication division, you're not going to get as close because the because you're multiplying and dividing so the numbers are gonna have more of an effect. But that's pretty close enough on do we say that? Be correct.

Problem we're being asked to find to being raised to the fifth Power. Well, if you recall what it means to do two to the fifth power is that we're going to take this number right here. The two and the exponent here tells us how many times we need to multiply two by itself. So because our exponents five, that means we have to take two and multiply it by itself five times. So we're gonna do two times. Two times two times, two times two. So let's do one at a time. So first, we're gonna multiply two times two? Well, two times two is equal to four. So now that leaves us with four times. Two times, two times two. Now let's multiply. Next summer's four times two is equal to eight. So now we have eight times. Two times two. Next, we're going to multiply eight times two, which is 16. So that leaves us with 16 times two. And lastly, we have 16 times two, which is equal to 32. And now we have found that two to the fifth is equal to 32

When we look at the frequency distribution, I am going to write it down here. We have the last digit and the frequency. So zero last digit is nine one, don't you? To one. Okay. Three. No, I'm just going off of the frequency disc distribution to give in our textbook seven and 08 39 and once. Now we can plot it into a frequency chart. Yeah, over here is going to be the last digit I'm gonna name it. Led because I do not wanna write it all down and over here is going to be the frequency which I'm gonna label f. So this is going to start from zero. And this is gonna zero, and it's gonna end at nine. Okay, so this Mr Graham is gonna look something like this. 09 So over here is nine. Okay? 12 21 33 41 5, 15. Which is gigantic 62 70 which is on the line here. 83 a 91 No. According to the above hissed a gram. The graph shows that there are many zeros and fives repeated. This means that day that the data is not measured appropriately. It shows that the data is not very accurate.

This is Problem eight of Chapter 14 in the second section, which is all about being critical off survey questions. So the question in this exercise is A Are you in favor of imposing a tax on tobacco to pay for health care related diseases caused by smoking? Um, health care related Over There is a two that's right health care related to diseases caused by smoking. So I in favor of imposing a tax on tobacco to pay for health care related to diseases caused by smoking. Um, for this one, I wouldn't say it's biased. Own sales confusing is long, Andi. That then, is an issue off this double bowel questions because if you think about that, you could cut off there. And that is a question. Are you in favor of imposing a tax on tobacco? Online itself is quite a good survey question isn't biased and sure it's simple. It's easy to understand, so finish it off that, but that you'll then extending it
