Sixty-eight percent of U.S. households own a pet, according to the 2017-2018 National Pet Owners Survey conducted by the American Pet Products Association (APPA). a. If 20 households are selected at random, let X be the number of households who own a pet. Determine if this is a binomial problem. Identify the number of trials, n, and the probability of success, p, for this problem: 1. 2. 3. 4. X~Binomial ( n =. b. Using excel, construct the probability distribution for this data. c. Find the probability that more than 10 of the 20 households have pets. P( d. Find the probability that less than 5 or more than 15 of the 20 households have pets. P( e. Find the probability that between 6 and 14 of the 20 households have pets. P( f. mean Interpretation: for the distribution tells us:Determine whether the given scenario meets the criteria of a binomial distribution. If not, identify the requirement that is not satisfied. If there is more than one requirement that is not satisfied, please indicate this by selecting the correct choice below. You ask seven randomly chosen college students if they went to the last football game or not.Use the scenario below to determine the correct values of n, p, q and x of the binomial distribution. Suppose that in a certain video game there is a 5.1% item drop rate of wild meat after defeating a Beast Master. Assume 14 Beast Masters are defeated. What is the probability that 5 wild meats will drop? n = p = q = X =
- 21n studies for a medication, 15 percent of patients gained weight as a side effect. Suppose 541 patients are randomly selected. Use the normal approximation to the binomial to approximate the probability that a) exactly 82 patients will gain weight as a side effect. (b) no more than 82 patients will gain weight as a side effect. (c) at least 92 patients will gain weight as a side effect. What does this result suggest? Click here to view the standard normal distribution table (page 1). Click here to view the standard normal distribution table (page 2). (a) P(82)= (Round to four decimal places as needed) www.It was found that 20% of people preferred the new user interface of a popular social media app. Assume you conducted a survey of 250 people. a. Explain why this experiment can be treated as a binomial distribution by selecting all of the necessary conditions. O One person's preference can influence someone else's. O The trials are dependent. O The trials are independent. O The survey is done multiple times. O There are only two options. O The probability of success never changes from trial to trial.

Suppose an airline has 47 seats and 54 tickets are actually sold. Use the continous probabily distribution to determine the probabilty that there will not be enough seats
- Construct a binomial distribution table for the number of defective computer chips in a lot of 4 if P=0.4. Round your answer to two decimal places.Suppose that 84% of all customers who use the service department at a certain automotive dealership would recommend the service to a friend. A random sample of 50 customers is taken. Canwe use the Normal distribution to compute probabilities about the sample proportion of thosewho would recommend the service to a friend? Why or why not?You are looking for the probability to draw 3 aces in 5 attempts from a deck of cards. There are 52 cards in the deck and 4 of them are aces. Explain why the poisson is not a good choice for describing this data-generating process. Which distribution would you use instead? No calculations necessary.
