Answer:

Step-by-step explanation:

5/6 is greater than 2/3
Multiply both numerator & denominator by 2 in order to have common denominators, 2/3 * 2/2 = 4/6
Now, you can see, 5 is greater than 4, in the numerator so 5/6 would be greater

Answer:
<h2>B. 7.1</h2>
Step-by-step explanation:
Given the sample data 2 6 15 9 11 22 1 4 8 19, before we can get the standard deviation, we need to first calculate the mean.
mean = 2 +6 +15 +9 +11 +22 +1 +4 +8 +19/10
mean = 97/10
mean = 9.7
Standard deviation for ungrouped data is expressed using the formula;



<em>Hence the standard deviation of the sample data is 7.1</em>
