Question 8

A researcher finds that Bulgarian immigrants in Canada have a mean English proficiency score of $$ 4.2  on a $$scale of $$ 1  to$$ $$ 5 . If $$the standard deviation is $$ 0.6 $$, what percentage of the group is expected to score between $$ 3.6 $$ and $$ 4.8 $$ assuming a normal distribution?

Accepted Answer

Question 9

Which of the following best explains why some adult learners never achieve native-like proficiency in a second language, according to the chapter?

Question 10

Accepted Answer

They may omit gender distinctions in L2, reflecting transfer from L1.

Question 13

Which of the following statements about first language knowledge and second language acquisition is supported by the chapter?

Accepted Answer
