Select one answer. In 2014, students in an advanced Statistics course at UC Berkeley conducted an anonymous survey about use of cognition-enhancing drugs among college 1o points males. One survey group of males included members from a fraternity, and the other survey of males group included no fraternity members. The difference between the proportion of fraternity members who have used cognition-enhancing drugs and the proportion of n members who have used cognition-enhancing drugs is equal to o.054. Which one of the following conclusions is true? on-fraternity A. O Students who are not fraternity members use cognition-enhancing drugs at higher rates than fraternity members. B. One possibility is that the proportion of fraternity members who have used cognition- enhancing drugs is 0.295 and the proportion of non-fraternity members who have used cognition-enhancing drugs is o.241. C. Students could have discovered that the proportion of fraternity members who have used cognition-enhancing drugs is o.315 and the proportion of non-fraternity members who have used cognition-enhancing drugs is o.369. c.

Which of these triangle pairs can be mapped to each other using two reflections?

{0,1,2,3,4,5,6,20,21,22,23,24,25} the distribution is considered to be: skewed the right, skewed the left, not skewed?

Cone w has a radius of 8 cm and a height of 5 cm. square pyramid x has the same base area and height as cone w. paul and manuel disagree on how the volumes of cone w and square pyramid x are related. examine their arguments. which statement explains whose argument is correct and why? paul manuel the volume of square pyramid x is equal to the volume of cone w. this can be proven by finding the base area and volume of cone w, along with the volume of square pyramid x. the base area of cone w is π(r2) = π(82) = 200.96 cm2. the volume of cone w is one third(area of base)(h) = one third third(200.96)(5) = 334.93 cm3. the volume of square pyramid x is one third(area of base)(h) = one third(200.96)(5) = 334.93 cm3. the volume of square pyramid x is three times the volume of cone w. this can be proven by finding the base area and volume of cone w, along with the volume of square pyramid x. the base area of cone w is π(r2) = π(82) = 200.96 cm2. the volume of cone w is one third(area of base)(h) = one third(200.96)(5) = 334.93 cm3. the volume of square pyramid x is (area of base)(h) = (200.96)(5) = 1,004.8 cm3. paul's argument is correct; manuel used the incorrect formula to find the volume of square pyramid x. paul's argument is correct; manuel used the incorrect base area to find the volume of square pyramid x. manuel's argument is correct; paul used the incorrect formula to find the volume of square pyramid x. manuel's argument is correct; paul used the incorrect base area to find the volume of square pyramid x.
