If the sample size is nequals9, what is the standard deviation of the population from which the sample was drawn?

13.33

Step-by-step explanation:

As in the attached diagram,  we can see that the points belong to   interval

Data provided in the question as per the details below:

= 440

= 480

So,

= 480 - 440

= 40

Now the standard deviation of the population is

= 13.33

Hence, the standard deviation of the population for which the sample is drawn is 13.33

the diameter is 16 cm. are you a teacher?

step-by-step explanation:

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
