Use the iqr rule to identify the outliers in this data set.
1,2,5,5,7,8,10,11,11,12,15,23

6.5

Step-by-step explanation:

1, 2, 5, 5, 7, 8, 10, 11, 11, 12, 15, 23

Median: 9

Lower quartile: 5

Upper quartile: 11.5

Interquartile range: 11.5 - 5 = 6.5

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.
