The average salary for American college graduates is $\$ 48,400$ . You suspect that the average is more for graduates from your college. The 53 randomly selected graduates from your college had an average salary of $\$ 51,937$ and a standard deviation of $\$ 9,140$ . What can be concluded at the $\alpha=0.05$ level of significance? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: $H_{0}$ : ? 웅 Select an answer 0 $\square$ $H_{1}$ : ? . 0 Select an answer $\square$ c.

The data suggest that the sample mean is not significantly greater than 48,400 at $\alpha=0.05$ , so there is statistically insignificant evidence to conclude that the sample mean salary for graduates from your college is greater than 51,937 . The data suggest that the population mean is not significantly greater than 48,400 at $\alpha=$ 0.05 , so there is statistically insignificant evidence to conclude that the population mean salary for graduates from your college is greater than 48,400.

3. Exkurs: Spurpunkte mit Anwendungen
In diesem Abschnitt werden als exemplarische Anwendungsbeispiele für Geraden Spurpunk, probleme behandell. Die Schnittpunkte einer Geraden mit den Koordinatenebenen bezeichnet man als Spurpunkte der Geraden.
Beispiel: Spurpunkte $\text { Gegeben sei g: } \vec{x}=\left(\begin{array}{l} 2 \\ 4 \\ 2 \end{array}\right)+r\left(\begin{array}{r} 1 \\ 1 \\ -1 \end{array}\right)$
Bestimmen Sie die Spurpunkte der Ge raden und fertigen Sie eine Skizze an.
Lösung: Der Schnittpunkt der Geraden mit der $x-y$ Ebene wird als Spurpunkt $S_{x y}$ bezeichnet. Er hat die $z$ -Koordinate $z=0$ . Die $z$ -Koordinate des allgemeinen Ge radenpunktes beträgt $z=2-r$ . Setzen wir diese 0 , so erhalten wir $r=2$ , was auf den Spurpunkt $S_{x y}(4|6| 0)$ führt. $\begin{array}{l} z=0: \Leftrightarrow 2-r=0 \quad \Leftrightarrow r=2 \\ \vec{x}=\left(\begin{array}{l} 2 \\ 4 \\ 2 \end{array}\right)+2 \cdot\left(\begin{array}{r} 1 \\ 1 \\ -1 \end{array}\right)=\left(\begin{array}{l} 4 \\ 6 \\ 0 \end{array}\right) \\ S_{x y}(4|6| 0) \end{array}$
Analog errechnen wir die weiteren Spurpunkte, indem wir die x-Koordinate bzw. die y-Koordinate des allgemeinen Geradenpunktes null setzen. - Ergebnisse: $S_{y z}(0|2| 4), S_{x z}(-2|0| 6)$
Übung 1 Berechnen Sie die Spurpunkte der Geraden g durch A und B. Fertigen Sie eine Skizze an. a) $\mathrm{A}(10|6|-1), \mathrm{B}(4|2| 1)$ b) $\mathrm{A}(-2|4| 9), \mathrm{B}(4|-2| 3)$ c) $\mathrm{A}(4|1| 1), \mathrm{B}(-2|1| 7)$ d) $\mathrm{A}(2|4|-2), \mathrm{B}(-1|-2| 4)$
