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:After several thousand game over several years versus a computer opponent, your instructor has won 66.4% of the time. At this rate, if twelve game were to be played what is the probability that he would win exactly eight of them? Explain your 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…
- Help pleaseYou need to compute the probability of 5 or fewer successes for a binomial experiment with 10 trials. The probability of success on a single trial is 0.54. Since this probability of success is not in the table, you decide to use the normal approximation to the binomial. Is this an appropriate strategy? Explain. O No, np 5. O No, np > 5. US V O 2:15 0% 8. 5Use the results of the file. Recall that you performed a binomial probability experiment 50 times. In Project #3, you will calculate a 99% Confidence Interval for the true probability of success, a 95% Confidence Interval, and a 90% Confidence Interval. Which of these intervals contain your original guess? None of them? All of them? Was your original guess accurate or inaccurate? Write a paragraph to explain. the data is in the file
- Illustrate the probability distribution if X is the random variable that represents the number of recovies.candy industries take random samples from their inventory and sort by flavor. daycare center samples a number of those they take care of and sort by how often they cry during a day visit. If you randomly select a candy from the candy sample and a child in daycare from the daycare sample, what is the probability that you'd pick a grape taffy and a child who cries more than twenty times a day?Suppose you are conducting a test of significance to try to determine whether your cat, Hope, will go to the correct object (out of two) when it is pointed to. You test Hope 100 times and finds she goes to the correct object in 70 out of those 100 trials. In this scenario, what is the variable? Whether or not Hope goes to the correct object The 100 trials The proportion of the 100 trials that Hope goes to the correct object The long term proportion (probability) that Hope will go to the correct object
