Answer:
(a) 4.152698
(b) 3.215557
Step-by-step explanation:
(a)

n=4, so :
Each subinterval has length :

Therefore the subintervals consist of:
![[1,5], [5,9], [9,13]](https://tex.z-dn.net/?f=%5B1%2C5%5D%2C%20%5B5%2C9%5D%2C%20%5B9%2C13%5D)
Now, the midpoints of these subintervals are:

Hence:

(b)

n=4, so :
Each subinterval has length :

Therefore the subintervals consist of:
[1,5], [5,9], [9,13]
The endpoints of the subintervals consist of:
5,9
Hence:
