Adults tend to believe that a majority of teenagers sleep in on Saturdays, but maybe that is a misconception. A random sample of 120 teenagers showed that 48 slept in the previous Saturday, Use the computer output provided
below to determine if there is convincing evidence at the a = 0,05 level that the true proportion of teenagers who
slept in on the previous Saturday is less than 0.5,
Use this computer output to answer the questions,
Based upon the 95% confidence interval, it is reasonable to claim that the true proportion of all teenagers who slept
in on the previous Saturday is between which two values?
O 0.3124 and 0.6876
O 0.3124 and 0.4877
O 0.4877 and 0.6876
O 0.5123 and 0.6876

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.
