(a)
To find: whether of the following scenarios explain a geometric setting yes or not, If yes than define an appropriate geometric random variable.
(a)

Answer to Problem 109E
No geometric distribution
Explanation of Solution
A random variable has a geometric distribution when the variable contain two possible results, every draw is independent of the previous ones, The variables computes the number of draws required until the first success. Every draw has the same
No geometric distribution, the reason is that does not count until the first success and interested in five successes.

(b)

Answer to Problem 109E
Geometric distribution
Explanation of Solution
A random variable has a geometric distribution when the variable contain two possible results, every draw is independent of the previous ones, The variables computes the number of draws required until the first success. Every draw has the same probability of success.
Every draw has the same probability of success
Geometric distribution, the reason is that the two possible results are win money and do not win money, draws are independent and compute the number of draws until the first success and

- Please help me answer the following question(c) A previous study found that 15% of nurses reported participating in mental health support programs.From the 96% found in (b) , can you conclude that proportion of nurses reported participating in mental health support programs p(current), has changed from the previous study?(Yes/No) because the confidence interval in (b) (captures/does not capture) 15%.(d) Refer to your answer in (b) : The Alberta Nurses Association expects that not more than 23 % of nurses will participate in the survey on mental health support programs. Given the result in part (b) can we conclude that this expectation is reasonable?(Yes/No) because the (upper bound/lower bound) of the 96% confidence interval is (less than/not less than/greater than) 23%.
