Recently, SouthwestAir had the best rate with 80 % of its flights arriving on time. A test is conducted by randomly selecting 12 Southwest flights and observingwhether they arrive on time.

Let Y have a binomial distribution with parameters n and p. We rejectH0 : p = 12 and accept H1 : p > 12 if Y ≥ c. Find n and c to give a power functionγ(p) which is such that γ( 12) = 0.10 and γ( 23) = 0.95, approximately.

Q3. Exponential Distribution has a memoryless property. Intuitively, it means that the probability of customerservice answering you call (assuming waiting time is exponential) in the next 10 mins is the same, no matter ifyou have waited an hour on the line or just picked up the phone. Formally, if X ∼ exponential(λ), f(x) = λ exp(-λx), and t and s are two positive numbers, use the definition of conditional probability to show thatP(X > t + s | X > t) = P(X > s).Hint: Find the cdf of X first, and note that P(X > t + s Ç X > t) = P(X > t + s)

T15 Suppose that 90% of drivers are "careful" and 10% are "reckless." Suppose further that a careful driver has a 0.2 probability of being in an accident in a given year, while for a reckless driver the probability is 0.4. What is the probability that a randomly selected driver will have an accident within a year? (Enter your answer to two decimal places.)
T2.5 The weekly number X of visits of the emergency department in a small town has a Poisson distribution with mean mu = 10 visits per week. Use Table A.2 to find the probability that a) the number of visits during a particular week exceeds 7. b) the number of visits during a two-week period is between 15 and 20, inclusive.

The time is known to have an exponential distribution with the average amount of timeequal to four minutes.i) Find the probability that a clerk spends four to five minutes with a randomly selected customer.ii) Find the probability that a clerk spends at least five minutes with a randomly selected customer.
The proportion of students who own a cell phone on college campus acress the country has increased tremendously over the past few years. It is estimated that approximately 90% of students now own a cell phone. Fifteen students are to be selected at random from a large university. Assume that the proportion of sudents who own a cell phone at this university is the same as nationwide. Let x = the number of students in the sample of 15 who own a cell phone. What is the appropriate distrubution for x?

James is supposed to take medication every night, but sometimes he forgets. He forgets to take his medication 3% of the time. Let X be the number of days next month (December) that James forgets to take his medication at night. X has a binomial distribution with parameters n = 31 and p = 0.03. Suppose we wanted to determine the chance James remembers to take his medication on exactly 27 days in December. Thus, we would be seeking P(X = ). What is the chance James forgets to take his medication exactly once in December? P(X = 1) = Express answer as a percent, rounded to the nearest integer. What is the chance James forgets to take his medication fewer than two times in December? P(X < 2) = Express answer as a percent, rounded to the nearest integer.
