The inside diameter of a randomly selected piston ring is a random variable with mean value 16 cm and standard deviation 0.04 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 cm standard deviation cm
(b) answer the questions posed in part (a) for a sample size of n = 64 rings. (enter your standard deviation to five decimal places.) center cm standard deviation cm

it would to have a graph or something ! but i had this question so its false

step-by-step explanation:

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw   congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.

replace   with   27   and simplify.

10 , 27 , 10 , 70 , 10 , 35 , 10 , 48
