After being rejected for employment, Kim Kelly learns that the Bellevue Credit Company has hired onlyfour women among the last 19 new employees. She also learns that the pool of applicants is very large,with an approximately equal number of qualified men as qualified women.Help her address the charge of gender discrimination by finding the probability of getting four or fewerwomen when 19 people are hired, assuming that there is no discrimination based on gender.Because this is a serious claim, we will use a strict cutoff value for unusual events. We will use 0.5% as thecutoff value (1 in 200 chance of happening by chance). With this in mind, does the resulting probabilityreally support such a charge?no, this does not support a charge of gender discriminationyes, this supports a charge of gender discrimination

The number of sampled employees, n=19.The number of selected employees that are women is 4.The…

In research, it is not practical to include all members of a population. Is this true or false
Consider a town with a population that is 10 percent black (and the remainder is white). Because blacks are more likely to work the night shifts, 20 percent of all cars driven in that town at night are driven by blacks. One out of every 20 people driving at night is drunk, regardless of race. Persons who are not drunk never swerve their car, but 10 percent of all drunk drivers, regardless of race, swerve their cars. On a typical night, 5,000 cars are observed by the police force. a. What percent of blacks driving at night are driving drunk? What percent of whites driving at night are driving drunk?b. Of the 5,000 cars observed, how many are driven by blacks? How many of these cars are driven by a drunk? Of the 5,000 cars observed at night, how many are driven by whites? How many of these cars are driven by a drunk? What percent of nighttime drunk drivers are black?c. The police chief believes the drunk-driving problem is mainly due to black drunk drivers. He orders his policemen to…

company records for 600 employees show that 120 have been reprimanded more than once and 450 have never been reprimanded. men make up 75% of the employees with more than one reprimand 50% of employees with no reprimanded and 50% of employees with one reprimand. assuming an employee is a woman what is the probablity that she has one reprimand?
4. For the two circumstances below, explain which type of probability (empirical, subjective, theoretical) is being used to make the prediction. If more than one type of probability is involved, explain which elements of the process use which of the methods. a. A scientist studying ants builds an ant farm and maps the routes they travel throughout the course of a week through careful observation. Later the scientist uses these observations to generate an interactive map of a natural environment that lists the probability of finding ants in any given location at a particular time. b. A social scientist studying grocery store accessibility in a city recruits a small sample of study volunteers and interviews them about how far they travel for groceries. The researcher finds in the study that people from higher-income neighborhoods travel significantly less than people from low-income neighborhoods. Using a statistical model, the researcher predicts that their sample has a 95% chance of…
3. Consider a roll of two 4-sided dice. A. How many members will the outcome set have? B. If the roll is considered "successful" if the numbers shown on the two dice add to 7 or 8, what are the members of the success set? C. What is the probability of a "successful" roll?
A problem with polling is whether or not people are willing to answer honestly. If a question might be viewed as shameful or embarrassing (about politics, sexual activity, etc.), they may be reluctant to answer honestly. A potential solution to this is the following: let's suppose that 'YES’ is the embarrassing or socially shameful answer. Give the people you are polling the following instructions: flip a coin privately, and if it comes up heads, you must answer honestly. However, if it comes up tails, you must answer 'YES’ regardless of what the truth is. This gives people л plausible deniability about why they answered yes, if pressed. Again, let p, be the fraction of people who said 'YES'. Let p be the probability that a randomly selected person says YES’. Let q be the probability that a person’s true answer is 'YES’. Note л again, we have that the expected value of p,, is p, but we are actually interested in N measuring q.
According to the Chronicles of Contrived Statistics (March, 2016), the probability that scientists from Area 51 will begin selling pet aliens in the next month is 37%. The probability that either Elon Musk will offer you a free trip to space or that scientists will begin sales of pet aliens next month is 44%. Finally, they list that probability of both happening in the next month is 22%. What is the probability that Elon Musk will offer you a free trip into space in the next month?
2. Rohan, the bookworm plans on reading 8 books by next week. But he only reads novels, poetry, short stories or science fiction. Interestingly he says, "My love for novels is twice the love for the rest altogether ". He also claims, "Love for short stories = 3 x Love for science fiction = 3 x Love for poetry". Taking these into account, determine the probability that he reads 4 novels, 3 poetry and 1 short story or science fiction?
A research wants to determine if pre-natal exposure to the hormones in birth control pills alters the sex makeup of midshipman fish populations (which are typically half male and half female).Specifically, the researcher wishes to test the hypothesis that exposure to hormones will increase the number of females in the population.The researcher exposes a group of pregnant midshipman fish to birth control hormones and records the sex of the first 9 offspring birthed.They then observe that 7 are female.Use a sign test to test the indicated hypothesis.What is the value of "significance"
If in a population 60% of people own an iPhone, 45% of people own an Android phone, and 37% own both types of phone. Are "owning an iPhone" and "owning an Android" independent outcomes? Cannot tell from the given information. Yes, they are independent. No, they are dependent.
