QUESTION 15 - 19.
Ten students who were struggling in a 3rd grade reading class were selected to take part in a Reading Is Fun program. Before the program, each student was given a pre-test; four weeks after attending the program students were given a post-test. Use the SPSS output below to study the question, did the Reading Is Fun program significantly increase students' scores? Use a .05 level of significance.
What is the critical value? Enter the value with three decimal places
Homework Answers
here degree of freedom =n-1=9
for 9 degree of freedom and 0.05 level with left tailed test , critical value t = -1.833 ( please remove the negative sign if sign is not required)
Add Answer to:
What is the critical value? Enter the value with three decimal places

A school counselor in a high school would like to try out a new conflict-resolution program to change aggressiveness in students. She first surveyed 16 students using a 20-item instrument to measure their levels of aggression (on a scale of 0 to 10, with higher numbers meaning higher aggression levels). One month after the conflict resolution program was implemented, the students were given the same survey. The data are listed in the table below. The school counselor/researcher has set the...

A teacher gives a test to her classes before and after showing them a particular educational video. A random sample of 15 of these students is selected. It was found that 5 of these students had a higher post- video test score, 9 of them had a lower post-video test score, and 1 student had equal pre- and post-video test scores. The sign test at the 0.2 significance level will be used to test the claim...
