There are different levels of measurement that have been classified into four categories. It is important for the researcher to understand the different levels of measurement, as these levels of measurement play a part in determining the arithmetic and the statistical operations that are carried out on the data.

In ascending order of precision, the four different levels of measurement are:

Answer:

0.48

Step-by-step explanation:

Given the data:

X:

10,17,20,23,24,28,32,39,42,25,26,52,55,58,61,65,66,72,75,78,79,85,94,97,98

Sum of each of the numbers :

1, 8, 2, 5, 6, 10, 6, 12, 6, 7, 8, 7, 20, 13, 7, 11, 12, 9, 12, 15, 16, 13, 13, 16, 17

Probability that sum of the number's digit is odd:

Number of odd sum / total numbers

Number of odd sum = 12

Total numbers = 25

12 / 25

= 0.48

I need to find a number that the "n" represents. The problem is 9/12=n/32
likoan [24]

The given equation is

\frac{9}{12} = \frac{n}{32}

Here we have to solve for n. First we need to get rid of the denominators and for that we do cross multiplication .

9*32 = 12n

Now we need to isolate n. And for that we need to get rid of 12, by dividing both sides by 12

\frac{9*32}{12}=n

\frac{288}{12} =n

n=24

And that's the required value of n .
