A total of 8 neutrinos, presumably from Supernova 1987A, as observed in an underground detector located in a salt mine near Cleveland.

(a) If the average number of "background" neutrinos observed per day is know to be 2, calculate the probability that 8 or more such background events will be detected in one day.

(b) If the average number of "background" neutrinos observed per day is know to be 2, calculate the probability that 8 or more such background events will be detected in a 10-minute period.

(c) Based on your answers to parts (a) and (b): Should the experimenters (call them Team A) who observe 8 or more events distributed over a one-day period publish their results as a "discovery," or simply attribute these "events" to a fluctuation in the background rate? If Team B observes 8 or more events within a 10-minute period, is this an important discovery, or likely statistical fluctuation?

Here are the observed frequencies from four categories: 5, 6, 8, 13. Assume we want to use a 0.05 significance level to test the claim that the four categories are all equally likely. (Goodness of fit test) What is the null hypothesis? What are the expected frequency for each of the four categories? What is the value of the test statistic? What is the critical value? What do you conclude about the given claim?

Question 1: Total 8 Marks 2017 December witnessed the government of Bandara inviting bids from eligible parties. The contract was about cell phone network construction. Youphone management got interested in the bid. Bandara had a poor land-line infrastructure and hence had a good potential for cell phone companies. If Youphone could successfully land few of these contracts, it would accomplish a high reputation for relevant expertise in the marketplace. Youphone management conducted extensive analyses before preparing and submitting a bid....
