A certain test preparation course is designed to help students improve their scores on the LSAT exam. A mock exam is given at th
e beginning and end of the course to determine the effectiveness of the course. The following measurements are the net change in 6 students' scores on the exam after completing the course: 6,16,19,12,15,14 Using these data, construct a 90% confidence interval for the average net change in a student's score after completing the course. Assume the population is approximately normal. Step 1 of 4 : Calculate the sample mean for the given sample data. Round your answer to one decimal place.
given that a certain test preparation course is designed to help 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 6 students' scores on the exam after completing the course:
the -2 will cause a reflection of the first equation in the x axis . then a translation down of 6.125 + 3.875 = 10 units , followed by a translation of -0.75-0.75 = -1.5 units to the right = 1.5
