IQR=4

Step-by-step explanation:

We have been given a data set that represents the number of rings each person in a room is wearing as: 0, 2, 4, 0, 2, 3, 2, 8, 6. We are asked to find the interquartile range of the data.

Let us arrange our data points from least to greatest order.

0, 0, 2, 2, 2, 3, 4, 6, 8.

Let us find median of our data set. Since our data set has 9 data points, therefore, median of our given data set will be value of 5th term, that is 2.

Now let us find lower quartile, which is also known as the median of the data points to the left of median.

We have 4 data points to the left of our median, so our lower quartile will be average of 2nd and 3rd data point.

$Q_1=\frac{0+2}{2}=\frac{2}{2}=1$

Now let us find upper quartile of our given data set, which is the median of the data points to the right of median.

We have 4 data points to the right of the median, so our upper quartile will be the average of 7th and 8th data point.

$Q_3=\frac{4+6}{2}=\frac{10}{2}=5$

Since we know that interquartile range is the difference between upper and lower quartile.

IQR=Q_3-Q_1

IQR=5-1

IQR=4

Therefore, IQR of our given data set is 4.

Interquartile Range = 4

Step-by-step explanation:

To find Inter Quartile Range (IQR) first we arrange the data set in ascending order to get Median.

0, 0, 2, 2, 2, 3, 4, 6, 8

In this data Median is the middle number "2"

Now we calculate Lower quartile

0, 0, 2, 2, 2, 3, 4, 6, 8

Find the median of left side data values of the median, there are two middle numbers so we take the mean

= $\frac{0 + 2}{2}$ = 1

Now calculate upper quartile

The median of right side data values of the median is called upper quartile, there are two middle numbers 4 & 6 so we take the mean

= $\frac{4 + 6}{2}$ = 5

Inter Quartile Range = Upper quartile - Lower quartile

IQR = 5 - 1 = 4

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.

The table shows the relationship between the number of cups of cereal and the number of cups of raisins in a cereal bar recipe: number of cups of cereal number of cups of raisins 8 2 12 3 16 4 molly plotted an equivalent ratio as shown on the grid below: a graph is shown. the title of the graph is cereal bars. the horizontal axis label is cereal in cups. the x-axis values are 0, 20, 40, 60, 80,100. the vertical axis label is raisins in cups. the y-axis values are 0, 10, 20, 30, 40, 50. a point is plotted on the ordered pair 40,20. which of these explains why the point molly plotted is incorrect? (a) if the number of cups of cereal is 40, then the number of cups of raisins will be10. (b)if the number of cups of raisins is 40, then the number of cups of cereal will be10. (c) if the number of cups of cereal is 40, then the number of cups of raisins will be 80. (d) if the number of cups of raisins is 40, then the number of cups of cereal will be 80.

Amachine that produces a special type of transistor (a component of computers) has a 2% defective rate. the production is considered a random process where each transistor is independent of the others. (a) what is the probability that the 10th transistor produced is the first with a defect? (b) what is the probability that the machine produces no defective transistors in a batch of 100? (c) on average, how many transistors would you expect to be produced before the first with a defect? what is the standard deviation? (d) another machine that also produces transistors has a 5% defective rate where each transistor is produced independent of the others. on average how many transistors would you expect to be produced with this machine before the first with a defect? what is the standard deviation? (e) based on your answers to parts (c) and (d), how does increasing the probability of an event aâ†µect the mean and standard deviation of the wait time until success?
