A statistically significant coefficient of 2 on average class size, K-3 implies:

a)That raising class size by 2 is associated with a 1 point increase in test scores

b)That raising class size by 1 is associated with a 2 point increase in test scores

c)That raising class size by 2 is associated with a 1 point decrease in test scores

d)That raising class size by 1 is associated with a 2 point decrease in test scores

Solutions

Expert Solution

Option b

Here, test score is a dependent variable and class size is an independent variable. As, the coefficient of class size is positive 2, it indicates that for every one unit increase in class size, the test score increases by 2 units.

A small community college claims that their average class size is equal to 35 students. This claim is being tested with a level of significance equal to 0.02 using the following sample of class sizes: 42, 28, 36, 47, 35, 41, 33, 30, 39, and 48. Assume class sizes are normally distributed. (NOTE: We need to assume that class sizes are normally distributed in order to use the t distribution because the sample size n=10 < 25, and the Central...
