Suppose the binomial experiment is a salesperson visits five customers and thediscrete random variable, x, is the total number of sales the salesperson makes(customers who make a purchase). How many experimental outcomes have the totalnumber of sales the salesperson makes equal to four? Enter your answer as a numberwith zero digits to the right of the decimal point.Your Answer:AnswerQuestion 2ListenSuppose the binomial experiment is a salesperson visits five customers and thediscrete random variable, x, is the total number of sales the salesperson makes(customers who make a purchase) and the probability of a sale on a sales call is 0.35.What is the probability the total number of sales the salesperson makes equalsthree? Enter your answer as a number with four digits to the right of the decimalpoint in the box shown below. Suppose the binomial experiment is a salesperson visits 6 customers and the discreterandom variable, x, is the total number of sales the salesperson makes (customerswho make a purchase) and the probability of a sale on a sales call is 0.50. What is theprobability the total number of sales the salesperson makes is less than 6?

The discrete random variable, x, is the total number ofcars arriving during a 20-minute period. Analysis of the restaurant's data shows thatthe average number of cars arriving during a 20-minute period of time is 6. What isthe probability that exactly 3 cars will arrive at the drive-up window of the restaurantduring a 20-minute period? Enter your answer as a number with four digits to theright of the decimal point in the box shown below.Suppose the experiment is operate a car dealership and the random variable, x, is thenumber of cars sold per day.

A group of 50,000 tax forms has an average gross income of $37,000, with an SD of about $20,000. Furthermore, 20% of the forms have a gross income over $50,000. A group of 900 forms is chosen at random for audit. What is the chance that between 19% and 21% of the forms chosen for audit have gross income over $50,000? (Show the box model and the result of your work.) Answer: %
see the photo for details The capacity of the stake supporting an electrical transmission tower is lognormal random variable with an average capacity of 1X0 tons and a variation coefficient of 3X (please type the last number of your student number instead of X). For example, if the last number of your student number is 4, the values will be 140 tons and 34%, respectively). What are the chances that the stake will remain intact under a load of 1X0 tons? (Instead of X, type the last number of your student number. For example, if the last number of your student number is 4, the value will be 140 tons) A pile loading test that is inserted during the placement of the stake indicates that the stake can support at least 85+X tons of load. What are the chances that the stake will remain intact under a load of 1X0 tons in such a situation? (Instead of X, type the last number of your student number. For example, if the last number of your student numara is 4, the values will be 89 tons…
Which of the following is not a random variable? The number of heads in ten tosses of a fair coin. The number of passengers in cars passing though a toll booth. The age of the driver in cars passing through a toll booth. The response of randomly-selected people to the question, “Did you eat breakfast this morning?” The response of randomly-selected people to the question, “How many hours of sleep did you get last night?"
You are doing research on balance and fitness. To complete this research you will need a watch with a second hand. Identify a random sample of n = 12 men and n = 8 women. You must answer this question: How do you establish that this sample is truly random? Have each subject perform the following task: Have the subjects stand with their hands at their side, raise one knee, cross their ankle over the other knee, squat and bring their hands palms together in front of their chest. Time the subject until they put their foot back down on the floor. b) Ask the following questions: i) How many days per week do they exercise? ii) What is their favorite exercise? You will analyze your data and compute the following statistics for each group: 1) The Mean and standard deviation of the number of seconds the subject stayed balanced 2) The Median number of days per week exercised 3) The Mode of the favorite exercise 4) The 90% confidence interval of the mean Construct a complete…
You want to examine the relationship between dropping out of high school and delinquency. You have a random sample of 11 students. You have the number of delinquent offenses that each student reported committing in the year before and after dropping out of school. The following table shows the data. Before dropping After dropping Student out out 1 7 2 9. 2 3 4 7 7 8 11 6 11 13 7 8 4 8 8 10 9. 5 7 10 2 1 11 3 From performing a hypothesis test to determine if the mean number of delinquent differs after dropping out, what is the p-value? (Round off to two decimal places if necessary)
When X is a binomial random variable, the mean of the probability distribution = np. A jury has 12 people on the jury. If a certain town has a population that is 9 percent a certain race, how many people of that race would you expect would be on the jury if jury selection was random (and every person was equally likely to be on the jury). Round answers to 4 decimal places as needed.
