skewed to the right
Step-by-step explanation:
The distance from the mean (110) of the remaining four numbers is presented bellow:
It can be observed that the numbers in the first and second quartiles are much closer to the mean than the numbers in the third and fourth quartiles, which means that there is more data on the left side of the distribution. This results in a longer right-tail, or a distribution skewed to the right.
3 metres from one end to the third mark
Solution:
Total length of wood = 10 metre
Wood is marked into 10 equal length.
= 1 metre
Length of each marking = 1 metre
Number of metres from one end to third mark = 1 + 1 + 1 = 3 metre
The image of the marking is attached below.
Hence 3 metres from one end to the third mark.
