answer the questions below based on the above presentation. place an x by yes or no. reduce fractions expressing probability to lowest terms.

in 3 billion repetitions of an experiment, a random event occurred in 500 million cases.

yes or no the probability of the event is 1.
yes or no the probability of the event is 0.
is the expected probability of this event.
is the expected probability of the complement of the event.

(b) suppose that consolidated power decides to use a level of significance of α = .05, and suppose a random sample of 100 temperature readings is obtained. if the sample mean of the 100 temperature readings is x⎯⎯ = 60.990, test h0 versus ha and determine whether the power plant should be shut down and the cooling system repaired. perform the hypothesis test by using a critical value and a p-value. assume σ = 5. (round your z to 2 decimal places and p-value to 4 decimal places.)
