Here is the transcription of the text from the image:---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 5 students' scores on the exam after completing the course:20, 26, 20, 11, 19Using 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 2 of 4: Calculate the sample standard deviation for the given sample data. Round your answer to one decimal place.Answer[How to enter your answer (opens in new window)][Submit Answer]© 2021 Hawkes Learning---The interface includes input options such as "Tables" and "Keypad" on the side, and there is a blank field for submitting an answer.
