Which measure of variation is found by placing the data in ascending order and subtracting the lowest value from the highest val

igomit [66]

Answer:

Range

Step-by-step explanation:

The range of a given set of data is the difference between the largest value and the smallest value in the data. For convenience and ease in the calculation, it is advisable to place the data in ascending order.

For example, given the following set of data:

4,9,5,6,2

To find the range;

=> First arrange the data in ascending order

2,4,5,6,9

=> Find the smallest and largest numbers and then find their difference.

Since the data has been arranged, it is obvious to see that the smallest number is 2 and the largest number is 9.

Therefore the;

range = 9 -2 = 7

mel-nik [20]

Answer: The required probability is 0.008.

Step-by-step explanation:

Since we have given that

Probability of bachelor's degree = 0.45

Probability of working in nursing = 0.85

Probability of both = 0.4

So, Probability of getting a graduate is currently working in nursing, given that they earned a bachelor's degree would be :

$P(N|B)=\dfrac{P(N\cap B)}{P(B)}\\\\P(N|B)=\dfrac{0.4}{0.45}\\\\P(N|B)=0.008$

Hence, the required probability is 0.008.
