Of all freshman at a large college, 16% made the dean's list in the current year. as part of a class project, students randomly sample 40 students and check if those students made the list. they repeat this 1,000 times and build a distribution of sample proportions. (a) what is this distribution called? (b) would you expect the shape of this distribution to be symmetric, right skewed, or left skewed? explain your reasoning. (c) calculate the variability of this distribution. (d) what is the formal name of the value you computed in (c)?

16 divided by 40 times 1000 divided by 3

Step-by-step explanation:

answer with step-by-step explanation:

a. ∠j is supplementary to ∠k - true:

(opposite angles of a trapezoid are supplementary which means that they add up to 180 degrees)

b. kl is parallel to jm - true:

(opposite sides are parallel to each other in a trapezoid)

c. jk is perpendicular to kl - false:

(clearly, jk does not make a right angle with kl)

d. jk is parallel to lm - false:

(jk and lm are two lines opposite in direction to each other so they cannot be parallel)

e. ∠j is congruent to ∠m - true:

(the angles on each side of the base are congruent)

f. ∠j is congruent to ∠k - false:

(the angles on the same side but opposite side of the base are not congruent)

i did it myself and i got 4.2 (b) hope its right
