For boys, the average number of absences in the first grade is 14 with a standard deviation of 4; for girls, the average number of absences is 9 with a standard deviation of 3. In a nationwide survey, suppose 100 boys and 64 girls are sampled. What is the probability that the male sample will have 4 to 6 more days of absences than the female sample? Round your answers to 4 decimal places.

addition

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.
