For each of the following action-selection methods, indicate which option describes it best. 1. With probability p, select argmaxaQ(s, a). With probability 1 — p, select a random action.
P =0.99

a. Mostly exploration
b. Mostly exploitation
c. Mix of both

2. Always select a random action.

a. Mostly exploration
b. Mostly exploitation
c. Mix of both

(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.)
