Answer:
So, the population mean is 3.66.
Step-by-step explanation:
We will calculate the average value by summing all the values and dividing by the size of sample.
We have population contains six members, with values 1,1,2,3,5,10.
Therefore, n=6.
We use the formula to calculate the population mean:

So, the population mean is 3.66.
Answer:
Step-by-step explanation:
Given that When n is divided by 21, the remainder is an odd number.
i.e.
where m is an integer and k a positive integer <21
When n is divided by 28, the remainder is 3
, where c is a positive integer
This can be written as

Since n is giving odd remainder when divided by 21,
we get r =3 as n is a multiple of 7 +3
It has been given in the question that Mary's team had lost 30% of the total of 20 games. There has been no ties for this team. It is required to find the number of matches that Mary's team lost.
Total number of games played = 20
Percentage of games lost by Mary's team = 30%
Number of games lost by Mary's team = (30/100) * 20
= 3 * 2
= 6
So Mary's team lost 6 games in all. I hope this is the answer you were looking for. The process is easy once you understand the words of the problem.
