Answer 1

Answer:

15

Step-by-step explanation:

Smallest number =10

biggest number =25

=10-25=15

Answer 2

Answer:

Step-µ =  

n

∑

i = 0

Xi

n

Input parameters & values

x1 = 5; x2 = 10, . . . . , x10 = 50

number of elements n = 10

Find sample or population mean for 5, 10, 15, 20, 25, 30, 35, 40, 45 & 50

µ =  

n

∑

i = 0

Xi

n

=(5 + 10 + 15 + . . . . + 50)

10

=275

10

= 27.5

Mean (5, 10, 15, 20, 25, . . . . , 45, 50) = 27.5

25 + 30

2

= 27.5

Median = 27.5
