Answer:
a)Both X and Y can be well approximated by normal random variables.
Step-by-step explanation:
For each individual, there are only two possible outcomes. Either they are right-handed, or they are left-handed. This means that we can solve this problem using concepts of the binomial probability distribution.
Binomial probability:
Probability of exactly x sucesses on n repeated trials, with probability p.
The binomial probability can be well approximated by normal random variables, using the expected value and the standard deviation
Let X be the number of males (out of the 100) who are left-handed.
and . Can be well approximated.
Let Y be the number of females (out of the 80) who are left-handed.
and . Can be well approximated.
The correct answer is
a)Both X and Y can be well approximated by normal random variables.
Answer:
Extraneous Solutions An extraneous solution is a root of a transformed equation that is not a root of the original equation because it was excluded from the domain of the original equation. Example 1: Solve for x, 1 x − 2 + 1 x + 2 = 4 (x − 2) (x + 2).
Answer:
100 times
Step-by-step explanation:
doesn't matter if the number is in the same place value so, the answer is 100 times.
Cheetahs population will be more affected by genetic drift
<h3>What is genetic drift?</h3>
Genetic drift is the change in a population's frequency of an existing gene variant brought on by chance. Gene variations may totally vanish due to genetic drift, hence reducing genetic variation. Additionally, it may lead to the considerably greater frequency and even fixation of previously rare alleles.
<h3>What causes genetic drift?</h3>
Random drift is a result of recurrently small populations, drastic population reductions known as "bottlenecks," and founder events in which a new population is created from a small number of individuals.
