G In a test of hypothesis, the null hypothesis is that the population mean is equal to 50 and the alternative hypothesis is that the population mean is greater than 50. Suppose we make the test at the 1% significance level. A sample of 121 elements selected from this population produces a mean of 58 and a standard deviation of 16.5. What is the value of the test statistic?

168

step-by-step explanation:

i am pretty sure that the answer is 168

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.
