Ten percent of the world's population is left-handed. A researcher claims that left-handed individuals are more creative than those who aren't left- handed. In order to support his claim, he takes a sample of 900 artists and finds that 11% of them are left-handed. a. Find the mean of ê, where is the proportion of left-handed individuals in a random sample of 900. b. Find the standard deviation of p. c. Compute an approximation for p (p20.11), which is the probability that there will be 11% or more left-handed people in a random sample of 900. Round your answer to four decimal places. (If necessary, consult a list of formulas.) X 5 ?

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.

i think it would be c
