Chapter 6: Q. 77 (page 358)

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

Expert verified

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

01

Given Information

The Trials is conducted n=7

Success of probability P=44%=0.44

02

According to the given question

The random variable X satisfies the following requirements:

a. Probability of success, defined as the likelihood of surviving to adulthoodpwhich corresponds corresponding0.44is 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.

A small ferry runs every half hour from one side of a large river to the other. The number of cars Xon a randomly chosen ferry trip has the probability distribution shown here with mean 渭X=3.87and standard deviation 蟽X=1.29. The cost for the ferry trip is $5. Define M=money collected on a randomly selected ferry trip.

a. What shape does the probability distribution of Mhave?

b. Find the mean of M.

c. Calculate the standard deviation of M.

Large Counts condition To use a Normal distribution to approximate binomial probabilities, why do we require that both npand n(1-p) be a t least 10?

Sally takes the same bus to work every morning. Let X=the amount of time (in minutes) that she has to wait for the bus on a randomly selected day. The probability distribution of Xcan be modeled by a uniform density curve on the interval from data-custom-editor="chemistry" 0minutesto8minutes. Define the random variable V=60X

a. Explain what Vrepresents.

b. What probability distribution does Vhave?

Benford鈥檚 law Faked numbers in tax returns, invoices, or expense account claims often display patterns that aren鈥檛 present in legitimate records. Some patterns, like too many round numbers, are obvious and easily avoided by a clever crook. Others are more subtle. It is a striking fact that the first digits of numbers in legitimate records often follow a model known as Benford鈥檚 law. 4 Call the first digit of a randomly chosen legitimate record X for short. The probability distribution for X is shown here (note that a first digit cannot be 0).

Part (a.) A histogram of the probability distribution is shown. Describe its shape.

Part (b). Calculate and interpret the expected value of X.

Airport security The Transportation Security Administration (TSA) is responsible for airport safety. On some flights, TSA officers randomly select passengers for an extra security check before boarding. One such flight had 76 passengers- 12 in first class and 64 in coach class. Some passengers were surprised when none of the 10 passengers chosen for screening were seated in first class. Should we use a binomial distribution to approximate this probability? Justify your answer.
