A class in New Zealand found a report suggesting that teenagers' heights in New Zealand are approximately normally distributed with a mean of 160 cm and a standard deviation of 15 cm. They thought the mean height
at their school was probably larger, so they took a random sample of n = 24 students. The mean height of
students in their sample was Ž = 166.5 cm.
To see how likely a sample like theirs was to occur by random chance alone, the class performed a simulation.
They simulated 80 samples of n = 24 heights from a normal population with a mean of 160 cm and standard
deviation of 15 cm. They recorded the mean of the heights in each sample. Here are the sample means from
their 80 samples:

215.92 dollars is the answer

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.
