Answer:
And for the deviation we have:
And that value represent the best estimator for the population deviation since:
Step-by-step explanation:
For this case we have the following data:
1.48,1.45,1.54,1.52,1.52
The first step for this cae is find the sample mean with the following formula:
And replacing we got:
And now we can calculate the sample variance with the following formula:
And replacing we got:
And for the deviation we have:
And that value represent the best estimator for the population deviation since:
If you reflect across the x-axis, the y value change from positive to negative.
If you reflect across the y-axis, the x value changes from positive to negative
Answer:
12.751
Step-by-step explanation:

--Subtract--
You can set this up as a proportion.
6/2.7=x/11.4
Cross multiply.
2.7x=68.4
Divide by 2.7 to solve for x
25.3333=x
