Andy had a snowball (a perfect sphere) with a radius of 3 \text{ cm}3 cm3, start text, space, c, m, end text. He wanted the snowball to be bigger, so he spent 444 seconds packing more snow onto it. Each second he spent packing, the snowball's radius increased by 0.25 \text{ cm}0.25 cm0, point, 25, start text, space, c, m, end text.
What is the ratio of the current volume of the snowball to the original volume of the snowball?

(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.)
