The management of seaside counseling services regularly monitors its counselors for speed of service with suicidal clients (i. e. minutes spent with clients before discharged). suppose a random sample of counselors was taken in 2005 and another random sample of counselors was selected in 2006. the results of the two samples are as follows:

counseling samples

2005 2006
1 = 225 2 = 219
s1 = 20.25 s2=21.70
n1 = 36 n2 = 31
based on the sample results, can the management of seaside counseling services conclude that average speed of service was different in 2006 than in 2005? conduct the appropriate hypothesis test at the 0.10 level of significance. assume that the management of the organization is willing to accept the assumption that the populations of service times for each year are approximately normally distributed with equal variances.

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.
