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:
For 5, what is happening is all the points shift down negative 2 on the Y axis and then flip over the x axis.
For 6, it would flip over the Y axis and start at positive 1 x the opposite
Answer:
equation of a line= y-y¹=m(x-x¹)
y--5=2(x-3)
y+5=2x-6
y=2x-6+5
y=2x-1
You must try to remove one of the unknown variables from the system by multiplying one in a way that when adding (or subtracting) one to another “makes it disappear” and so whatever value you get can be substituted back in to get the other unknown!
