For a software company, a candidate has a success rate of p = 0.3 for each attempt in their interview. An examinee applies for the company 5 times consecutively. He doesn't want a job. He is just messing with the company. 1.What is the probability that the candidate gets the job 3 times within these 5 interviews? 2.What is the variance for this probability distribution? 3.What is the probability that he was successful at most 2 times?

Suppose you are throwing an outdoor lunch event for a group of 300 people. Wanting to be inclusive, you decide to offer vegetarian options. Since you thought of vegetarians at the last minute, you are not sure how many are attending, but a quick google search shows that vegetarianism occurs at a rate of 5% according to a recent poll. Assume that the requirements for a binomial distribution have been satisfied. What is the probability that you will have more than 10 vegetarians attending your event? What is the probability that you will have less than 20 vegetarians attending your event? Find the mean number of vegetarians that you would expect to attend this event. Create a “usual range” of the number of vegetarians that you would expect to attend such an event Max usual range: Min usual range:

Air-USA has a policy of booking as many as 26 persons on an airplane that can seat only 22. (Past studies have revealed that only 85% of the booked passengers actually arrive for the flight.)Find the probability that if Air-USA books 26 persons, not enough seats will be available. Round your answer to 4 decimal places.prob =Is this probability low enough so that overbooking is not a real concern for passengers if you define unusual as 5% or less?a. Since the probability is above 5%, this should be a concern b. Since the probability is below 5%, this should not be a concern

Jenny works for a local brewing company. She and her team mates try to estimate the Hong Kong consumers’ preference on their beer brand compared to other imported ones. They performed a survey asking if the respondent prefers the company’s brand the most or not. Based on this survey result, they want to decide how much money the company needs to invest on brand promotions in the coming year. This is an important decision for the company, and the management wants to have the probability that the sample proportion p is +/- 3% from the actual proportion p to be very high (i.e., at least 99%). In this case, what is the desirable sample size n for the following two cases? Give the answer in the form of: at least ___ x100 samples. Case i. When the actual proportion is 50%. Case ii. When the actual proportion is 10%. Explain why the sample sizes required to achieve the same accuracy in the two cases are different.
Suppose you did an experiment with 3 groups and 16 subjects per group. The sample variances in the three groups were 14, 16, and 18. Using Tukey's test to compare the means, what would be the two-tailed probability for a comparison of the first mean (14) with the last mean (18)?
