Candice wants to estimate the proportion of the freshmen at her high school that likes sports drinks. She interviews a simple random sample of 75 of the

215 freshmen on campus. She finds that 18 students like sports drinks. Is the Normal condition for finding confidence intervals met? Explain.

- Yes, the Normal condition for finding confidence intervals is met because no = 18 and n(1-P) = 57, both of which are greater than 10.

- Yes, the Normal condition for finding confidence intervals is met because the sample size is greater than 30.

- No, the Normal condition for finding confidence intervals is not met because np = 18 and n(1-P) = 57, both of which are less than 100.

- No, the Normal condition for finding confidence intervals is not met because the sample is not at least 50% of the population.

- Yes, the Normal condition for finding confidence intervals is met because the sample is a simple random sample.

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
