Question (12-17) Refers to the Following: A study was conducted in Mankweng City to examine the modes of transport that workers use for their daily commutes, along with the distances traveled by each mode of transport. Test at \( 1 \% \) level of significance if the mode of transport is independent of the distance traveled by these sampled workers The information is summarised in Table 1. Table 1: Distance traveled by each mode of transport. \begin{tabular}{|c|c|c|c|c|} \hline \multirow[b]{2}{*}{Distance} & \multicolumn{3}{|c|}{Mode of transport} & \multirow[b]{2}{*}{Total} \\ \hline & Bus & Taxi & Car & \\ \hline <10 km & 15 & 21 & 22 & 58 e \\ \hline 10-15 km & 30 & 27 & 17 & 74 C \\ \hline \( >15 \mathrm{~km} \) & 23 & 19 & 26 & 68 \\ \hline Total & 68 & 67 & 65 & 200 \\ \hline \end{tabular} 12. What are the null \( \left(\mathrm{H}_{0}\right) \) and alternative hypotheses \( \left(\mathrm{H}_{1}\right) \) for this Chi-square test? A. The mode of transport is independent of the distance traveled and the mode of transport is dependent on the distance traveled. B. Mode of transport is dependent on the distance traveled and The mode of transport is independent of the distance traveled. C. The distance traveled is not equal to the mode of transport and The distance traveled is equal to the mode of transport. D. The distribution of transport modes follows a normal distribution and The distribution of transport modes doesn't follow a normal distribution. E. None of the answer is correct 13.

Q2) A steam engine has a boiler that works at a pressure of X. Saturated water with a flow rate of X enters the boiler and leaves at the same rate as saturated steam. The boiler is fired by a fuel that has a lower heating value (LHV) of Xs. The saturated steam enters the reciprocating engine and leaves as weak steam at a pressure of X with a quality of Xs. This weak steam enters, then, the condenser and leaves as saturated water at 101.325 kPa. The condenser is cooled by water with Cp = X kJ/kg with a temperature difference of Xs. Consider the following: Calculate the following: 1. The efficiency of the boiler is X. 2. Power input to the boiler [kW]. 3. The density of the fuel is X. 4. Heat losses in the boiler [kW]. 5. The efficiency of the engine is X. 6. The volume flow rate of the fuel in [L/h]. 7. Engine Power output [kW]. 8. The heat removed by the condenser [kW]. 9. Required mass flow rate of the condenser cooling water [kg/s]. X.
