Find the values at the 30 th and 90 th percentiles for each set of values.
$\begin{array}{lllllllll}{7} & {12} & {3} & {14} & {17} & {20} & {5} & {3} & {17} & {4} & {13} & {2} & {15} & {9} & {15} & {18} & {16} & {9} & {1} & {6}\end{array}$

And this problem, we have six test scores only are asked to find the percentile that corresponds to each you'll be using this formula. P equals number of numbers lower plus 0.5 over end. Where n is the total number of numbers Times 100 to convert 12%. So we need to identify how maney numbers we have. And we said this is six test scores. So for this problem and equal six, all right. So to calculate the first percentile for the corresponds to test score five. How Maney data values are lower than five and that answer is zero. So we ads. You're a 0.5 divide by six and multiplied by 100. That turns out to be 8.33333 etcetera. So 8.3 repeating, and that working around them corresponds to about the eighth percentile. So for the data value of 12 we have one data value lower than 12. So we're gonna have one plus 10.5, divide by six and multiply by 100. So 1.5 divided by six uh, and then multiply by 100 is 25. So that corresponds then to 25th percentile. Say I'm going to repeat that same pattern. And for 15 we have two values lower. So 2.5 divided by six times 100 and that gives us 41.6, which is going around then to the 42nd percentile. And we're going to continue in that same fashion for the last three numbers. So we've got three numbers less than 16 and when you compute, that comes out to be 58.3, which rounds to the 58th percentile and then four plus 40.5. I'm just gonna go ahead and write 4.5, divided by six and multiply by 100 and that gives us the 75th percentile. And then our last number. We have five numbers less than that. So five plus 50.5 is 5.5, divided by six multiplied by 100 and that corresponds to or that equals 91.7, which is the 92nd percentile. So, um, you may notice that there's a little bit of a pattern that these air evenly spaced, and that makes sense because if we look at 100% split six ways, we've got six data values. It turns out to be 16 0.6 repeating percent. So if you keep adding 16.6% you'll make your way through that. And that's the pattern. It's in that table, All right. For the last part of the problem, we are asked to find the 33rd percentile. So we need to use the other formula. C equals end times p over 100 where n is equal to the number of numbers and P is the percentile. So in this case, 33 make that a multiplication sign there, um, divided by 100 and that comes out to be 1.98 So that means we're looking for the number in the 1.898 position. Um, since that's not a specific position, we round up when we always round up. So that means we're looking for the number that's in the second position. So if we go back and look at our data, then number 12 is right here. That's in our second position. Our second number when we look at the data organized from smallest to largest. So the 33rd percentile Oops, um, is what was that? 12

So we just want to look for the outlier in this list, so just kind of looking at it. They are all two digit numbers except for one. And that one is zero. So zero is the outlier in this.

So we arranged the values given to us in the order. And we get to task. 5581 57 0057 005896 Then we have 5972 59 93 Sig 07 Fight 6 to 74 6 to 8 today. 6381 Okay, so this is the secret that we get and we have to find the 30 it percentile. Andi, 98% time. So 38%. I will be turkey multiplied by turkey, divided by 100. Which is going to be night on. This will be 40 30 it on this will be 40 90. It Carty multiplied by. I do divided by 100. So this will be 27. So now what do you see? This is 12 tree full by 678 night on. After that, what do you get? Is the number off the A person died. So you want we get we get per butte percentile us So be it percentile as six today It one on the 90th percentile does not exist

So we have 20 pieces of data in this set and instead of listing them all, you can actually go in there and see what is less than or equal to 6.5. Well if you look at the data, there are four That are less than or equal to 6.520 pieces of data, so four divided by 20 Gives us the 20th%ile. 7.7 has nine pieces of data equal to or less than that. And when I reduce that, I get 45th%ile.
