n the following random experiment, decide whether the random variable X is binomial or not:Approximately 1 in 10 people are left-handed. Let X be the number of people that are left-handed out of a random sample of 200 individuals. Although the individuals are sampled without replacement, it is assumed that we are sampling from such a vast population that the selections are virtually independent.Group of answer choicesNot binomialBinomial

In the following random experiment, decide whether the random variable X is binomial or not:A sample of 4 cards is selected without replacement from a standard deck of 52-cards, in which there are 26 red and 26 black cards. Let X be the number of cards that are red. Binomial Not binomial

According to a recent national poll, 41% of females and 32% of males identify as democrats. Suppose a random sample of 120 females and 140 males is obtained.What is the value of the parameters for the binomial random variable X, the number of democrats in the sample of 120 females?n =   (report your answer in whole numbers)p =   (report your answer to two decimal places)

Which one of the following  is likely to be well described by a Binomial model?Group of answer choicesThe number of accidents in a large factory during one 8-hour shiftThe number of spades in a bridge hand (ie a random selection of 13 cards from a pack of 52 cards)The number of tosses of a fair coin until the 10th head is obtainedThe number of years between floods at a certain locationThe number of apples that are 'infected' in a sample of 40 apples randomly selected from a large consignment of apples.

For the binomial distribution, (nx)𝑛𝑥px(1 − p)n − x, represents the probability of any particular sequence with x successes and n − x failures. Use this formula to answer the following: In the Southern area of the United States, approximately 20% of adults have a college degree. We randomly ask four adults whether they have a college degree. What is the probability that none of the adults have a college degree?Multiple choice question..512zero.16.4096

A Gallup Poll in May 2004 estimated that roughly 70% of U.S. adults are in favor of the death penalty for a person convicted of murder. A random sample of 750 U.S. adults is chosen. Let X be the number of adults (out of 750) who favor the death penalty.The distribution of X is binomial. What are the values of n and p?
