About 30% of bables born with a certain ailment recover fully. A hospital is caring for seven babies bc babies that recover fully. Decide whether the experiment is a binomial experiment. If it is, identify a su values of the random variable x. Is the experiment a binomial experiment? O No O Yes What is a success in this experiment? O Baby doesn't recover O Baby recovers O This is not a binomial experiment. Specify the value of n. Select the correct choice below and fill in any answer boxes in your choice. O A. n= OB. This is not a binomial experiment.

A survey asks 1400 workers, "Has the economy forced you to reduce the amount of vacation you plan to take this year?" Fifty-six percent of those surveyed say they are reducing the amount of vacation. Twenty workers participating in the survey are randomly selected. The random variable represents the number of workers who are reducing the amount of vacation. Decid whether the experiment is a binomial experiment. If it is, identify a success, specify the values of n, p. and q, and list the possible values of the random variable x. Is the experiment a binomial experiment? O No Yes

Which of the following is a benefit of randomization when compared to repetition?   A. Randomization takes more time   B. Randomization allows for the variation due to machine setup to be captured   C. Randomization requires resetting the equipment between tests   D. Randomization is less complicated

In a recent survey, it was stated that Americans watch television on average four hours per day. Assume that σ = 2. Using your class as the sample, conduct a hypothesis test to determine if the average for students at your school is lower. a. Find Ho and Ha b. In words, define the random variable. _____ = _________________ c. The distribution to use for the test is ______________

A poll found that 35% of adults do not work at all while on summer vacation. In a random sample of 7 adults, let x represent the number who do not work during summer vacation. Complete parts a through e. C a. For this experiment, define the event that represents a "success." Choose the correct answer below. Adults working during summer vacation Adults not working during summer vacation b. Explain why x is (approximately) a binomial random variable. Choose the correct answer below. O A. There are three possible outcomes on each trial. OB. The experiment consists of only identical trials. OC. The trials are not independent. D. The experiment consists of identical trials, there are only two possible outcomes on each trial (works or does not work), and the trials are independent. c. Give the value of p for this binomial experiment. p= 0.35 d. Find P(x= 3). P(x= 3) = (Round to four decimal places as needed.)

ZOC Page < 8 of 8 shape: shape: shape: 4. Owning a Pet. 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:

Roll a die until you get 7 twos and count the number of rolls required. Does this process describe a binomial random variable? If it is binomial, give values for n and p. If it is not binomial, enter NA in both entry fields. n = p =

A state lottery randomly chooses 6 balls numbered from 1 through 45 without replacement. You choose 6 numbers and purchase a lottery ticket. The random variable represents the number of matches on your ticket to the numbers drawn in the lottery. Determine whether this experiment is binomial. If so, identify a success, specify the values n, p, and q and list the possible values of the random variable x. B. Yes, the probability of success is the same for each trial. OC. Yes, there are a fixed number of trials and the trials are independent of each other. D. No, there are more than two outcomes for each trial. Identify a success. Choose the correct answer below. OA. A success is matching one of the numbers in the lottery. B. A success is the number of matches on your ticket to the numbers drawn in the lottery OC. A success is matching all of the numbers in the lottery. D. The experiment is not binomial. Specify the values n, p, and q. Select the correct choice below and, if necessary,…
