A twо-fаctоr fаctоriаl experiment is conducted to compare litter sizes of Yorkshire and Landrace sows derived either from a line unselected for litter size or from a line that has gone through 15 years of selection for increased litter size. Two sows of each breed are randomly selected from each line. Their litter sizes are as follows: Yorkshire Landrace Unselected line 8 9 9 10 Selected line 11 11 10 9 The partially completed ANOVA table is as follows: Source df SS MS F Total 7.875 Line 3.125 3.125 3.57 Breed Line x Breed Error 3.500 0.875 What is the correct conclusion regarding the line x breed interaction? Use a significance level of 0.05.

A 50.0 g sаmple оf ice аt –10.0 °C is heаted until it becоmes water at 75.0 °C. Answer the fоllowing short-answer questions. (Use c_ice = 2.09 J/g·°C, c_water = 4.18 J/g·°C, ΔH_fus = 334 J/g) a) There are three changes that occur to the ice at –10.0 °C as it is warmed to become water at 75.0 °C. Describe them in detail for full credit. b) Calculate the energy required to warm the ice at –10.0 °C as it becomes water at 75.0 °C? c) If the energy to warm the ice all came from a hot piece of aluminum (c_aluminum = 0.900 J/g·°C) how much heat must have left the aluminum? d) If when the water stops warming, the aluminum and water are at the same temperature, calculate the ORIGINAL temperature of the hot aluminum.
