You would like to know how effective a diet program is at helping people lose weight. 18 over-weight people are randomly selected to participate in the program. They are weighed before and after the program and the results are listed below. Do these results give evidence that the diet program is effective at the 1% significance level?

3 Let $\leq_P$ be the relation of reduction: $L_0 \leq_P L_1$ if there is a polynomial-time reduction $\rho: (0+1)^* \to \newline 0+1)^*$ such that $\newline \forall \sigma \in (0+1)^*: [\sigma \in L_0 \iff \sigma \in L_1]. \newline Show that the $\leq_P$ relation is a transitive relation on languages. That is, show that if $L_1 \leq_P L_2$ and $\newline L_2 \leq_P L_3$, then $L_1 \leq_P L_3$.

V. Thomas and E. Simmons (1969). Problem 1 The data in Table 4.3 are a subset of the data obtained by Thomas and Simmons (1969), who investigated the relation of sputum histamine levels to inhaled irritants or allergens. The histamine content was reported in micrograms per gram of dry weight of sputum. The subjects for this portion of the study consisted of 22 smokers; 9 of them were allergics and the remaining 13 were asymptomatic (non-allergic) individuals. Care was taken to avoid people who carried out part of their daily work in an atmosphere of noxious gases or other respiratory toxicants. Table 4.3 gives the ordered sputum histamine levels for the 22 individuals in the study. Test the hypothesis of equal levels versus the alternative that allergic smokers have higher sputum histamine levels than non-allergic smokers. Use the large-sample approximation.

1. Connecting to a Calculus Concept: Concavity The function $f(x) = x^2$ is concave up. One way to define this property for the function $f(x) = x^2$ is: If $P = (a, a^2)$ and $Q = (b, b^2)$ are two unique points on the graph of $f(x) = x^2$ then the line segment PQ (except the endpoints at a and b) always lies above the graph of $f(x) = x^2$. (a) Sketch a graph that illustrates the statement above. (b) Find the slope of the line that passes through any points P and Q. Notice anything interesting about the simplified value for the slope? Explain. Verify it with an example. (c) Find the equation of the secant line that passes through any points P and Q and algebraically verify that the midpoint of segment PQ lies above the parabola. (d) Explain verbally how the conclusion from your algebraic verification in (c) proves that the midpoint of segment PQ lies above the parabola.

1.45 LAB: Pizza party Given the number of people attending a pizza party, output the number of people, number of pizzas needed, and the total cost for the number of pizzas. For the calculation, assume that people eat 2 slices on average and each pizza has 12 slices and costs $14.95. Output each floating-point value with two digits after the decimal point using the following statement: print(f'Cost for {numPizzas} pizza(s): ${cost:.2f}') Hint: Use the ceil() function from the math module to round up the number of pizzas so that enough pizzas are ordered. Ex: If the input is: 20 the output is: People: 20 Pizza(s): 4 Cost for 4 pizza(s): $59.80
