Q. A Histogram shows that the mean of rain in the area has increased over the last 5 years. What is the probability that the mean would be higher this year than in the previous 5?
Q. A hot (70^{circ}C) lump of metal has a mass of 250 g and a specific heat of 0.25 cal/g.^{circ}C. John drops the metal into a 500 g calorimeter containing 75 g of water at 20^{circ}C. The calorimeter is constructed of a material that has a specific heat of 0.10 cal/ g. ^{circ}C. When equilibrium is reached, what would be the final temperature? c_{water} = 1.00 cal/g.^{circ}C.
