Student Testing Question Below... True or False:?

The registrar at a community college wanted to determine if there was a difference in the average test scores students made in two different classes. The data she accumulated are:





Class A: mean = 126; sample sd = 10.7; class size = 16


Class B: mean = 118; sample sd = 5.4; class size = 10.





For a given 伪-value, the registrar should use a ';testing the difference between 2 means with dependent samples'; technique..





True





FalseStudent Testing Question Below... True or False:?
False. Since there is no guarantee that the same students are in both classes, this is an indpendent sample situation comparing two means.
