Agallup poll of 1236 adults showed that 12% of the respondents believe that it is bad luck to walk under a ladder. consider the probability that among 30 randomly selected people from the 1236 who were polled, there are at least 2 who have that belief. given that the subjects surveyed were selected without replacement, the events are not independent. can the probability be found by using the binomial probability formula? why or why not?
choose the correct
a)no. the selections are not independent, and the 5% guideline is not met.
b) no. the selections are not independent
c) yes. although the selections are notindependent, they can be treated as being independent by applying the5% guideline.
d) yes. there are a fixed number of selections that areindependent, can be classified into twocategories, and the probability of success remains the same.

He graph of f(x) = |x| is stretched by a factor of 0.3 and translated down 4 units. which statement about the domain and range of each function is correct? the range of the transformed function and the parent function are both all real numbers greater than or equal to 4. the domain of the transformed function is all real numbers and is, therefore, different from that of the parent function. the range of the transformed function is all real numbers greater than or equal to 0 and is, therefore, different from that of the parent function. the domain of the transformed function and the parent function are both all real numbers.
