You can try to solve it by hit and trial method as x and y are both natural numbers.
x = 5 and y = 2
x+y = 7
Answer:
The standard deviation for the number of people with the genetic mutation in such groups of 1000 is 9.49.
Step-by-step explanation:
Standard deviation: It is a measure of how spread out numbers are. It is the square root of the Variance, and the Variance is the average of the squared differences from the Mean.
The given parameters are:
Proportion, p = 10%
Sample size, n = 1000
The standard deviation is calculated as:
σ=
So, we have:
σ=*(1-10%)
Evaluate:
σ= 9.49
Hence, the standard deviation for the number of people with the genetic mutation in such groups of 1000 is 9.49.

Step-by-step explanation:
Answer:
=SUM(C2:C4, C7)
Step-by-step explanation:
In excel 'C' represent the cell ( intersection of row and column ),
Also, '=sum( )' represents the function of addition in the excel,
Also, when we operate all consecutive cells from to
Then under the function formula we write
And, when we operate a cell with non consecutive cell
Then under the function formula we write
Hence, C2+C3+C4+C7 can be written as,
=SUM(C2:C4, C7)
