Solve it and you get 1/8 easy.
Let m be mean
Mean= sum/ n
Mean= (1720+1687+1367+1614+1460+1867+1436) / 7
m= 11151 / 7
M= 1593
Mean= 1593
Standard deviation
|x-m|^2
For 1st: |1720-1593|^2=8836
For 2nd: |1687-1593|^2=10201
For 3rd: |1367-1593|^2=51076
For 4th: |1614-1593|^2=441
For 5th: |1460-1593|^2=1689
For 6th: |1867-1593|^2=75076
For 7th: |1436-1593|^2=24649
Summation of |x-m|^2 = 171968
Standard deviation sample formula is:
S.D = sqrt((summation of |x-m|^2) / n-1)
S.D=sqrt(171968/6)
S.D=sqrt(28661.33)
S.D=169.30
Standard deviation is 169.30
Area of the room that needs to be carpeted = 121 ft^2
Since the carpet is sold only in square meters, so the area of the room needs to be converted to square meters from square feet. Most of the information's required to solve this question is already given.
We know
1 ft^2 = 0.09290304 m^2
So
121 ft^2 = 0.09290304 * 121 m^2
= 11.24 m^2
So 11.24 square meters of carpet is required.
