The inside diameter of a randomly selected piston ring is a random variable with mean value 15 cm and standard deviation 0.06 cm. (a) if x is the sample mean diameter for a random sample of n = 16 rings, where is the sampling distribution of x centered and what is the standard deviation of the x distribution? (enter your standard deviation to five decimal places.)

Center = 15, SD=0.00375

Step-by-step explanation:

population and sampling distribution will have the same center. In this case, the center of the sampling distribution would be 15cm.

S E = σ/  sqrt n

=0.06/16

x = 17

step-by-step explanation:

1st step: isolate x.

24 - 3x = -27

-24         -24

-3x   =   -51

2nd step: divide.

-3x     =   -51

  3             3

  x       =     17

hope this

8

step-by-step explanation:

just put √(2) * √(32) into a calculator. that will make the answer be 8.
