Sample size 5 5
Mean rate 6.2 5.3
Mean diffference = 
Std error for difference = 0.25 (given)
Since we have two groups and also sample sizes are very small we can use t significant value for finding out confidence interval
df = 5+5-2 =8
t critical value for 80% two tailed = 1.397
Conf interval 80%
=
48 students in group 2
43 students in group 1
