A random sample of households in Orange County showed that 23 out of 192 of them were burglarized in the past 5 years. And in a random sample of households in Cook County, 17 out of 233 of them were burglarized in that same time period. We will test the claim that the proportion of Orange County households that were burglarized ($p_1$) is not equal to the proportion of Cook County households that were burglarized ($p_2$). For each part below, enter only a numeric value in the answer box. For example, do not type "z =" or "t =" before your answers. Round each of your answers to 3 places after the decimal point. (a) Calculate the value of $\bar{p}$, the pooled sample proportion, that is used in this hypothesis test. $\bar{p}$ = (b) Calculate the value of the test statistic used in this test. Test statistic's value = (c) Use your calculator to find the $P$-value of this test. $P$-value = (d) Use your calculator to find the critical value(s) used to test this claim at the 0.01 significance level. If there are two critical values, then list them both with a comma between them. Critical value(s) =

PART A - HEAT TRANSFER 16-CHEM-A3, Heat and Mass Transfer May 2019 1) (a) [15 points] The inside and outside surface of a hollow sphere at $r = r_1$ and $r = r_2$ ($r_1 < r < r_2$) are maintained at temperatures $T_1$ and $T_2$. The thermal conductivity ($k$) varies with temperatures as $k = k_o (1 + aT + bT^2)$, where $k_o$, $a$ and $b$ are constants. Derive an expression for heat flow $Q$ through the sphere. (b) [10 points] A plane wall with isothermal faces $T_1$ at $x = 0$ and $T_2$ at $x > 0$ has thermal conductivity ($k$) that varies with temperature given by expression $k = k_o (1 + aT)$, where $k_o$ and $a$ are constants. Derive an expression for heat flow $Q$ through the wall.
