Acertain test preparation course is designed to students improve their scores on the lsat exam. a mock exam is given at the beginning and end of the course to determine the effectiveness of the course. the following measurements are the net change in 66 students' scores on the exam after completing the course: 18,19,13,7
using these data, construct a 99% confidence interval for the average net change in a student's score after completing the course. assume the population is approximately normal.
calculate the sample standard deviation for the given sample data. round your answer to one decimal place.

the first question mark is 6 and the second question mark is 26 (the square root)

step-by-step explanation:

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
