Approximately 10% of all people are left-handed. Consider 12 randomly selected people. a) State the random variable. rv X = the number of 12 randomly selected people that are left-handed b) List the given numbers with correct symbols. nv = 12 pv = 0.1 c) Explain why this is a binomial experiment. Check all that apply. Whether or not one randomly selected person is left-handed will affect whether or not another randomly selected person is left-handed There are only two outcomes for each person There are a fixed number of people, 12 Whether or not one randomly selected person is left-handed will not affect whether or not another randomly selected person is left-handed Op = 10% remains constant from one randomly selected person to another There is not a fixed number of people There are more than two outcomes for each person

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:
GC content in Plasmodium falciparum genome is 40%. Assume that each base pair in the genome has equal probability of being GC.a. What is the probability of finding no AT pairs if 4 pairs were randomly chosen?b. What is the probability of finding 3 or more AT pairs in 4 pairs?
A survey asks 1100 workers, "Has the economy forced you to reduce the amount of vacation you plan to take this year?" Forty-six percent of those surveyed say they are reducing the amount of vacation. Ten workers participating in the survey are randomly selected. The random variable represents the number of workers who are reducing the amount of vacation. Decide 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? No Yes What is a success in this experiment?

The proportion of brown M&M's in a milk chocolate packet is approximately 14%. Suppose a package of M&M's typically contains 57 M&M's. a) State the random variable. b) List the given numbers with correct symbols. = 57 = 0.14 c) Explain why this is a binomial experiment. Check all that apply. There are more than two outcomes for each M&M There are a fixed number of M&Ms, 57 Whether or not one randomly selected M&M is brown will not affect whether or not another randomly selected M&M is brown There is not a fixed number of M&Ms There are only two outcomes for each M&M p = 14% remains constant from one randomly selected M&M to another Whether or not one randomly selected M&M is brown will affect whether or not another randomly selected M&M is brown Find the probability, to 4 decimal places: It is possible when rounded that a probability is 0.0000 d) exactly none are brown. e) exactly 54 are brown. f) at least…
