Question

Baby elk Biologists estimate that a randomly selected baby elk has a 44 % chance of surviving to adulthood. Assume this estimate is correct. Suppose researchers choose 7 baby elk at random to monitor. Let X= the number that survive to adulthood.

Short answer

The given statement is correct because According to biologists, a baby elk chosen at random has a 44 percent chance of living to adulthood.

Step-by-step solution

Given Information

The Trials is conducted $\left(\mathrm{n}\right)=7$

Success of probability $\text{P=44\%=0.44}$

According to the given question

The random variable X satisfies the following requirements:

a. Probability of success, defined as the likelihood of surviving to adulthood$\left(\mathrm{p}\right)$which corresponds corresponding$\text{0.44}$is now fixed.

b. The number of baby elk chosen is set.

c. Baby elks are completely self-sufficient.

d. There are two possible outcomes: either the newborn elk survives to adulthood or it does not.

Here, all of the binomial criteria are met. As a result, it is possible to conclude that X the binomial distribution is followed.
