16 Determine whether the underlined value is a parameter or a statistic. A study of 6,076 adults in public rest rooms found that \( 23 \% \) did not wash their hands before exiting. Is the value a parameter or a statistic? A. The value is a statistic because the 6,076 adults in public rest rooms are a sample. B. The value is a parameter because the 6,076 adults in public rest rooms are a population. C. The value is a statistic because the 6,076 adults in public rest rooms are a population. D. The value is a parameter because the 6,076 adults in public rest rooms are a sample.

The equilibrium constant, \( K_{\mathrm{c}} \), for the following reaction is 55.6 at 698 K . \[ \mathrm{H}_{2}(\mathrm{~g})+\mathrm{I}_{2}(\mathrm{~g}) \rightleftharpoons 2 \mathrm{HI}(\mathrm{g}) \] Calculate the equilibrium concentrations of reactants and product when 0.372 moles of \( \mathrm{H}_{2} \) and 0.372 moles of \( \mathrm{I}_{2} \) are introduced into a 1.00 L vessel at 698 K . \( \left[\mathrm{H}_{2}\right]=\square \mathrm{M} \) \( \left[\mathrm{I}_{2}\right]=\square \mathrm{M} \) \( [\mathrm{HI}]=\square \)

Task one - fuel cost Key information from the first page is repeated here: - The one-way distance from Northcote College to Tongariro Alpine Crossing is 350 km . - The current fuel price is \( \$ 2.62 \) per litre. - The school vans use 7.2 litres of fuel per 100 km travelled. - Each of the school vans can fit a maximum of 10 people. - The government is considering a \( 17 \% \) fuel tax to be added to the cost of fuel prior to the trip, which could be in place before the camp. 1. Calculate the cost of fuel per person for a return trip to Tongariro Alpine Crossing from Northcote College. 2. If a fuel tax increases the fuel price, then calculate how this could change the total fuel cost. 3. Discuss any assumptions or limitations you have made and how they impact your calculations.
