Complete: Chapter 3 Problem Set A school district is deciding whether or not to adopt a new reading curriculum. Three classrooms are randomly selected as test sites for the curriculum. To obtain a measure of student improvement, students in the three classrooms are tested on their vocabulary before and after the curriculum is implemented. The vocabulary test has 25 possible points. The post-implementation scores for the students in the third classroom are shown in the following table: 19 13 16 18 15 14 17 8 20 19 22 11 Calculate the sample size, $n$; the total sum, $\sum X$; and the sample mean, $M$. n = $\sum X$ = M = The school district decides it will be easier to understand the scores if they are converted to a 100-point scale. This requires that each score be multiplied by 4. Calculate the new $n$, $\sum X$, and $M$. n $\sum X$ = M =
