Answer: 7.94
Step-by-step explanation:
The formula to calculate the standard deviation for binomial distribution :-
, where n is the number total of trials and p is the probability of getting success in each trial.
Given : The probability of the population has a particular genetic mutation=0.1
If 700 people are randomly selected, then the standard deviation for the number of people with the genetic mutation in such groups of 700 will be :-
Hence, the standard deviation for the number of people with the genetic mutation in such groups of 700 = 7.94
Check the picture below.
let's recall that the midsegment of a triangle is the segment that's half-way to both endsides and is at the same time parallel to the 3rd side, is also half the length of the parallel side, so-called the base.
so, for example, we know L, M and N are midpoints to each segment, that means that LM is a midsegment and parallel to PR and also half the length of PR, same is true for LN and MN.
