Answer:
for sample = xbar
population = μ
Step-by-step explanation:
The arithmetic mean for sample can be represented by xbar and it can be calculated as
xbar=∑xi/n
Where xi represents data values and n represents number of data values in a sample.
The arithmetic mean for population can be represented by μ and it can be calculated as
μ=∑xi/N
Where xi represents data values and N represents number of data values in a population.

<u><em>Answer: 1/11 and 0.09=0.10</em></u>
Step-by-step explanation:
subtract by the numbers. subtract it's to take away one number from to another from the difference between the numbers.

5-4=1
=1/11
You can also round up to the nearest hundredths is 0.10.
Hope this helps!
Thanks!
Have a great day!
Answer:
56
Step-by-step explanation:
z varies jointly with x and y:
z = kxy
When x = 2 and y = 2, z = 7.
7 = k(2)(2)
k = 7/4
z = 7/4 xy
When x = 4 and y = 8:
z = 7/4 (4)(8)
z = 56
THE answer is 17 because 2X2= 4+13= 17
Your Welcome :D
