Answer the following statement(s) true (T) or false (F)
A random sample of 11 Wistar rats can learn a T-maze in 12 trials, on average, with a standard deviation of 4. A random sample of 11 wild rats can learn a T-maze in 8 trials, on average, with a standard deviation of 3. The observed result was t_obs=((m_1-m_2 ))/s_(m_1-m_2 ) = –2.65. Therefore, the 95% confidence interval around the estimate effect size (d) is [0.23, 2.04]
Ans: F
