Name 4. For this question you will be determining the heat capacity (J/g) of the calorimeter using the data provided. Like Equation 4, all of the heat lost by the hot metal had to transfer to the water and the calorimeter. You should read through the background material before completing this question. $|q_{lost \text{ by hot iron}}| = |q_{gained \text{ by room temperature water}}| + |q_{gained \text{ by calorimeter}}|$ Show calculation work, with units, for credit Mass of Calorimeter 15.690 g Mass Room Temp. Water 52.700 g Mass of Iron 72.875 g Temperature of Room Temperature Water 20.63°C Initial Temp. of the Hot Water 100.03°C Final Temperature of the 29.59°C system $\Delta T$ for water $\Delta T$ for Iron Specific Heat of Water 4.184 J/g °C Specific Heat of Iron 0.450 J/g °C q Gained by the water q Lost by the Iron q Gained by Calorimeter

Group Females Males n 509 396 Mean 3.07 2.86 (a) Set up the hypotheses of a significance test to analyze whether the population means differ for females and males. ---Select-- 2 Ha: 1 ---Select--- - 2 (b) Conduct all parts of the significance test if df = 508 and standard error = 0.164 . Interpret the P-value, and report the conclusion for = 0.05. t = (3 decimal places, positive value) p-value= (3 decimal places) (c) Conclusion O There is evidence that females, on average, watch more TV than males. O There is evidence to conclude that there is a gender difference in TV watching. O There is not enough evidence to conclude that there is a gender difference in TV watching. (d) If you were to construct a 95% confidence interval comparing the means, would it contain 0? O Yes, because according to the test o is a plausible value for the difference between the population means. O No, because according to the test o is a plausible value for the difference between the population means. O No, because according to the test o is not a plausible value for the difference between the population means O Yes, because according to the test o is not a plausible value for the difference between the population means.

A new bridge with a 100-year life is expected to have an initial cost of $20 million. This bridge must be resurfaced every five years, at a cost of $1 million. The annual inspection and operating costs are estimated to be $50 000. Determine the present-worth cost of the bridge using the capitalized equivalent approach (i.e., take the life of the bridge as infinite). The interest rate is 10% per year, compounded annually.
