Men women
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%
=
Area = b*h and in some cases * 2 so you need to do this, 64*52 + 40*28= 4448 yd2
7*100+2*1= 702
10+5*1= 15
702+15= 717
i hope that is really does help if it don't i am sorry
