Answer:
a) The mean μ = 719,16
The median is the middle number m = 711
The mode is the number that occurs more often
md = 700
b) The range r = 67
The standard deviation σ = 25.63
I ( 95 % ) = ( 667.90 ; 770.42)
Step-by-step explanation:
We order the set of numbers in ascending order
682 687 689 693 694 700 700 700 703 706 707 710 711 712 713 730 732 734 736 739 752 753 759 768 769
The mean μ = Σ xi/n
μ = 719,16
The median is the middle number
m = 711
The mode is the number which occurs more often
md = 700
The range is r = 769 - 682 r = 67
c) Interval with 95 % of observations is ( μ + 2σ ; μ- 2σ )
I = ( 719.16 - 2*25.63 ; 719.16 + 2*25.63)
I ( 95 % ) = ( 667.90 ; 770.42)
