Stock Prices A random sample of stock prices per share (in dollars) is shown. Find the 90 $\%$ confidence interval for the variance and standard deviation for the prices. Assume the variable is normally distributed. $$ \begin{array}{cccc}{26.69} & {13.88} & {28.37} & {12.00} \\ {75.37} & {7.50} & {47.50} & {43.00} \\ {3.81} & {53.81} & {13.62} & {45.12} \\ {6.94} & {28.25} & {28.00} & {60.50} \\ {40.25} & {10.87} & {46.12} & {14.75}\end{array} $$

Okay and this question we need to tell the sequence which is correct. Okay so we are given our data and for that we need to find the value of me. Okay, first of all I mean is equal to uh delta affects divided by DELTA F. Support. That first the first a step would be that we will find the value of sigma F. And sigma fx. So RB option will be the first option. Which the option is that we are finding the value of delta fx. Okay and we are finding the value of delta F. So the option is the first step. Now in the second step we will be obtaining the value of sigma efforts and sigma F. So the option will be done second sequence. Okay. The option will be that we will be obtaining our delta effects and DELTA F. So the is the second step now in the third step we will be applying the formula of meal. Okay we'll be putting the value of uh sigma Fx and sigma F. And the value in the formula of me. So when third step will be the applying the formula of me, that is sigma fx divided by sigma. Now in the 4th step we will be getting our means right? So this is the correct sequence which is B b C. Sorry, it's me, yeah, it's B b C. And A. Okay, here is a. Okay, that's it. Thank you.

So in this question, we're going to be looking at finding quartile. One court help, too. Quart l three, the mid quartile and the I Q. R for these given data sets for these two given data sets. So here's our first data set, and the numbers are arranged in order from smallest to largest, which is critical when you're finding measures of position. And so we're going to start by looking for court l two quart l two is also known as the media. So 2 2/4 50% right the middle. So we have 123456 numbers, So an equal six. So if I take six and divided by two, that gives me three. That means my median is halfway between the third and the fourth data value. So if I look here, here's my third of my fourth data value on I want what's right in between. So to find quartile, too, I'm going to add 16 and 25 together and divide by two. In other words, I'm gonna find their average, find out what's in the middle of them, and that tells me that I get in the middle there to be 20 point. So there's quartile too. Then I'm gonna separate the data into two halves. The lower half of the upper house so kind of down the middle here and the middle of the lower half is quartile one, and we could just see by looking at it. So the middle number there is poor tell one. On the middle of the ball of the upper did are the hard data values is court L three. So we can just look at those two things on inspection. So quartile one is 12 and court tell three equals 32. All right, so then we've gotta find what's called the mid quartile, and it is essentially the average of the first and the third court trials. And we're given this formula in the problem Q one plus Q three divided by two So we can substitute these two values in. So the mid quartile is going to be 12 plus 32 divided by two. And that gives us 22. And finally we're gonna find the I Q r and the I Q r. Um, is Q three minus Q. One. It's just the difference. The range of the court tiles, so that is equal to 30 to minus 12 which gives us 20. So there we have our five answers moving on then, too. Ah, the numbers and data set B the same. We have seven numbers. So when we have seven numbers, we want to find the median on and we can find the median position. When we have a non number of numbers, we can add one and divide by two. So that means our median is going to be the number that's in the fourth position. So that means this number right here, 94 Hotel two, which is equal to the median, is 94. All right, so then to find court, tell one I'm gonna look for the middle of the lower half of numbers and again it jumps right out at us. We can just look at it and see that the median, um, or the middle of the lower half of numbers is 62 and same procedure for the top half of numbers. We can see them. That court L three is equal to 99. All right, so now we can move on to the mid court tile And that's when we looked at in the last data set there. We're gonna add our foretells together and divide by two. So 99 plus 62 divided by two gives us 80.5. And then our last calculation we need to do is Thea like you are, which is equal to quartile three minus court l one. So we have 99 minus 62 which gives us 37. So 37 80.5 and then we've got our core tell to at 94 quartile one at 62 court l three at 99 okay?

So we're going to start this problem by putting our data in numerical order. So that's going to give me a 10 12 23 23 24 25 26 28 20. Done soaring on 34. So put the numbers in order because then you can see where the middles are and make it well, easier on yourself. Range. Take your top monitor bottom. So 31 minus 10 means that my range is 21. This is my range as far as my I. Q. Argos, I need to find some court trials. So I need the middle. So find the middle of your data. That's gonna be the middle number. So we're not going to use that number. That's our median. But on the bottom, this would be your bottom number. That's the middle down there. This is the middle of here, so your I Q r is gonna be 29 minus 23 which is six. Now, if you're gonna test for out liars, you're gonna take that I Q R times one point, uh, which gives you not so we can't be more than non under the lower or non above the upper. So taking your your quartile, you're gonna subtract it from the bottom one, which gives you 12 notice that 10 is less than 12. So definitely have an outlier down there on the top in, you have 29 plus nine, which is 38 and 31 falls within that 30 that number. So we're good on the top it So what we have We have a range of 21 an I Q. R of six and one outlier at the bottom of Burdick.

In this problem, we have to find mean and standard deviation using this shortcut method. So here, in this table, we have given the following information. Now let's assume mean As equals to 64. Now, in order to find mean, first of all, we will find a fellow anyway for that we will find you, y It would be equals two ex aa minus assumed me. So here we get 16 -64 is- Fool. Stephen -64 is -3, 60 to -64 is -2, 63 -64 is -1, 64. -64.0 65 -64 is one, 66 -64 is too 67 -64 is three, 68 -64 is full. Now we will find I find your way, it would be 22 -4 is -8. one in 2 -3 is -3. 12 into -2 is -24, into -1 is -29, 25 in 20 is 0, 12 into one is 12. Turn into two is 20 four in 2, three is 12 and five into 4 is 20. Now we know that Mean is equals two assumed mean plus submission of F I U I A born and Here we have submission of FIUY is zero. So by substituting the known values in this formula we get mean is equals true 64-plus 0.00. It would be equals to 64. Now, in order to find standard evasion. First of all, we will find if I into you a square it would be 32 nine 48 29 zero, 12, 40 36 and 18. And the submission of Fiui square is 286. As we know that standard aviation as equals two, one upon in and root and in two sigma, f i u i square minus sigma, f i u I whole square. By substituting the known values, we get. Standard deviation is equals to one upon 100 and the root 102 286 0 sq. It would be equals to 1-100 into under route 28,600, Which is equals two one of 102, 169.1. So we get standard deviation is equal to 1.69. Hence we get standard aviation Is equal to 1.69.
