I would like some detailed explanation to the follow statistical methods exercises

Determine the best distribution to model this scenario: Hot Mondays Session has a strict over 18 policy. The arrival of patrons that look under the ag of 18 is evenly distribution over a 4-hour period. What is the probability that it will take more than 2 hours before someone who looks under the age 18 to arrive? Select one: O a. None of the listed options b. Exponential O c. Uniform O d. Binomial O e. PoissonX A graduate student augments his scholarship by tutoring at a rate of $300 per hour and working as an office assistant which pays $500 per hour. On red average he tutors 2.40 hours per week with a standard deviation of 1.39 hours. While, on average, he works 1.25 hours per week as an office 1.00 assistant, with a variance of 0.77 hours. If he saves the difference between what he makes tutoring and what he makes from being an office assistant, what is the variance of his savings per week? Select one: O a. $283.18 O b. $802.00 O c. $876.08 O d. $32.00QUESTION 7 Determine the best distribution to model this scenario: If an average of 500 persons in a constituency voted for the P Not yet answered probability that you find more than 650 persons in the North East St Mary constituency that voted for the PNP? Marked out of 1.00 Select one: Flag O a. Binomial question O b. Poisson O c. Exponential O d. Uniform O e. None of the listed options Next
