What forms of violence do you think are most significant or prevalent in the United States today? Which ones are you most concerned about right now? Why? What programs/policies are in effect on your campus to prevent violent attacks? Would you know what to do if a campus lockdown occurred?

A normal pack of playing cards contains 52 cards. These are made up of four suits (hearts, diamonds, clubs and spades. Each suit consists of 13 cards. These are labelled Ace, 2, 3, 4, 5, 6, 7, 8, 9, 10, Jack, Queen and King. The hearts and diamonds are red; the clubs and spades are black. If a card is picked at random from a normal pack of cards, calculate the probability of picking: a) a heart, b) not a heart, c) a 4, d) a red King, e) a Jack, Queen or King, f) the Ace of spades, g) an even numbered card, h) a 7 or a club.

You pay $10 and roll a die. If you get a 6, you win$50. If not, you get to roll again. If you get a 6 this time, you get your $10 back. a) Create a probability model for this game. b) Find the expected value and standard deviation of your prospective winnings. c) You play this game five times. Find the expected value and standard deviation of your average winnings. d) 100 people play this game. What’s the probability the person running the game makes a profit?

Recall that blocking refers to the idea that we can reduce the variability in a variable by segmenting the data by some other variable. The given data represent the recumbent length (in centimeters) of a sample of 10 males and 10 females who are 40 months of age.

$$\begin{array}{lc|cr} \text{Males}&&\text{Females}\\ \hline 104.0 & 94.4 & 102.5 & 100.8 \\ \hline 93.7 & 97.6 & 100.4 & 96.3 \\ \hline 98.3 & 100.6 & 102.7 & 105.0 \\ \hline 86.2 & 103.0 & 98.1 & 106.5 \\ \hline 90.7 & 100.9 & 95.4 & 114.5 \\ \end{array}$$

What effect does blocking by gender have on the standard deviation of recumbent length for each gender?

Rec all that blocking refers to the idea that we can reduce the variability in a variable by segmenting the data by some other variable. The given data represent the recumbent length (in centimeters) of a sample of 10 males and 10 females who are 40 months of age.

$$\begin{matrix} \text{Males} & \text{ } & \text{Females}\\ \text{104.} & \text{94.4} & \text{102.5} & \text{100.8}\\ \text{93.7} & \text{97.6} & \text{100.4} & \text{96.3}\\ \text{98.3} & \text{100.6} & \text{102.7} & \text{105.0}\\ \text{86.2} & \text{103.0} & \text{98.1} & \text{106.5}\\ \text{90.7} & \text{100.9} & \text{95.4} & \text{114.5}\\ \end{matrix}$$

Determine the standard deviation of recumbent length for all 20 observations.

The celebrated example due to Karl Weierstrass of a nowhere differentiable continuous function $f(x)$ in $-\infty<x<\infty$ is given by

$$f(x)=\sum_{n=0}^{\infty}\left(\frac{3}{4}\right)^n \phi\left(4^n x\right),$$

where $\phi(x+2)=\phi(x)$, and $\phi(x)$ on $0 \leqslant x \leqslant 2$ is the "triangle" through $(0,0),(1,1),(2,0)$. By construction, $0 \leqslant \phi\left(4^n x\right) \leqslant 1$. Verify by means of the comparison test that the series converges for any value of $x$. [See Counterexamples in Analysis by B. R. Gelbaum and J. M. H. Olmsted, HoldenDay, San Francisco (1964), p. 38 for the proof that $f$ is nowhere differentiable.]
