Arandom sample of 100 people was taken. eighty of the people in the sample favored candidate a. we are interested in determining whether the proportion of the population in favor ofcandidate a is significantly more than 75%. (1) the test static (z ) the p value ) at a 0.05 of level significance, it can be concluded that the proportion of the population in favor of candidate a: (a) is significantly greater than 75% (b) is not significantly greater than 75% (c) is significantly greater than 80% (d) is not significantly greater than 80% (e) none of the above answers is correct.

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.

10 b/c 5*2 =10
