schwester practice exams volume 2 exam2 morning session question 23
Did anybody find there are wrong answers for schwester practice exams?
For example, in schwester practice exams volume 2 exam2 morning session question 23,
for the covariance, I think the denominator is 5 instead of 4 which make the answer A instead of B. Am I wrong? |
