Answer:
x = - 2 or x = 4
Step-by-step explanation:
the expression inside the absolute value can be positive or negative
Removing the bars and solve x - 1 = ± 3
x - 1 = - 3 or x - 1 = 3
x - 1 = - 3 ( add 1 to both sides ) ⇒ x = - 2
x - 1 = 3 ( add 1 to both sides ) ⇒ x = 4
The upper 70th percentile is the number below which 70% of the data lie.
The 70th percentile position is given by:
![P_{70}= \frac{70N}{100} = \frac{70(36)}{100} =25.2](https://tex.z-dn.net/?f=P_%7B70%7D%3D%20%5Cfrac%7B70N%7D%7B100%7D%20%3D%20%5Cfrac%7B70%2836%29%7D%7B100%7D%20%3D25.2)
Thus, the 70th percentile position is approximately the 25th data item (after the data has been arranged in acsending order).
Given the following data:
<span>16 24 25 26 27 29 36 39 39 39 40 44 45 47 47 48 50 51 51 53 53 54 57 58
58 60 65 66 67 69 69 71 72 74 74 74
The 25th data in the data set is 58.
Therefore, the upper P70 is 58.
