Some people feel that violence in fiction and on TV (like the violence in Poe's story) results in real-life violence. How do you feel about this?

Nielsen reported that young men in the United States watch 56.2 minutes of prime-time TV daily (The Wall Street Journal Europe, November 18, 2003). A researcher believes that young men in Germany spend more time watching prime-time TV. A sample of German young men will be selected by the researcher and the time they spend watching TV in one day will be recorded. The sample results will be used to test the following null and alternative hypotheses.

$$\begin{array} { l } { H _ { 0 } : \mu \leq 56.2 } \\ { H _ { \mathrm { a } } : \mu > 56.2 } \end{array}$$

What is the Type II error in this situation? What are the consequences of making this error?

Solve the given problems.

If a TV camera is $x$ m from the launch pad of a $50$-m rocket that is $y$ m above the ground, find an expression for $\theta$, the angle subtended at the camera lens.

Retaliation is a cause of violence. How might retaliation create an environment in which the level of violence tends to escalate continually?

A thin soap film $(n=1.33)$ suspended in air has a uniform thickness. When white light strikes the film at normal incidence, violet light $\left(\lambda_{\mathrm{V}}=420 \mathrm{~nm}\right)$ is constructively reflected. If we would like green light $\left(\lambda_{\mathrm{G}}=560 \mathrm{~nm}\right)$ to be constructively reflected, instead, should the film's thickness be increased or decreased?

Color photographic films are designed for particular wavelength sensitivities such as "daylight" and "indoor incandescent lighting." An incandescent lightbulb radiates approximately as a blackbody at $3200 \mathrm{~K}$, while daylight is approximately like a blackbody at $5800 \mathrm{~K}$. Make some calculations and comment on the results that might be obtained if a film is used for other than its intended light source, that is to say, daylight film with indoor lighting.

A camera is used to photograph a kitten. The camera is equipped with a standard lens that has a focal length of $50 \mathrm{~mm}$. The camera is focused by moving the lens closer to or farther away from the film at the back of the camera. (a) First the kitten is photographed when it is $350 \mathrm{~mm}$ (13.8 in.) in front of the camera lens. Use the lens formula to compute the distance that the lens must be from the film for the image to be in focus. (b) Compute the magnification and the height of the image, assuming that the kitten is $100 \mathrm{~mm}$ tall. (c) The kitten is then photographed from a distance of $3,500 \mathrm{~mm}(11.5 \mathrm{ft})$. Compute the lens-to-film distance, the magnification, and the image height.

Due to the no-slip condition, as a solid is pulled out of a viscous liquid some of the liquid is also pulled along as described in the mentioned example and shown in the mentioned video. Based on the results given in the mentioned example, show on a dimensionless plot the velocity distribution in the fluid film $\left(v V_0\right.$ vs, $\left.x / h\right)$ when the average film velocity, $V$, is $10 \%$ of the belt velocity, $V_0$

Paulie often stays up late watching old movies on the television Program film classics.

If you increase the aperture diameter of a camera by a factor of 3, how is the intensity of the light striking the film affected? Increasing the aperture doesn't affect the intensity.

Rashid had $24\frac { 11 } { 16 }$ feet of cable wire. She cut off a $13 \frac { 5 } { 8 }$-foot piece to hook up her cable box, then she cut off a $5\frac { 1 } { 4 }$-foot piece to connect her cable box to her TV. Is the remaining piece as long as the wire that connects the cable box to the TV?

The article “Viewers Speak Out Against Reality TV” (Associated Press, September 12, 2005) included the following statement: “Few people believe there’s much reality in reality TV: a total of $82\%$said the shows are either ‘totally made up’ or ‘mostly distorted’.” This statement was based on a survey of 1002 randomly selected adults. Compute and interpret a bound on the error of estimation for the reported percentage.

Certain mushrooms launch their spores by a catapult mechanism.

As water condenses from the air onto a spore that is attached to the mushroom, a drop grows on one side of the spore and a film grows on the other side. The spore is bent over by the drop’s weight, but when the film reaches the drop, the drop’s water suddenly spreads into the film and the spore springs upward so rapidly that it is slung off into the air. Typically, the spore reaches a speed of 1.6 m/s in a 5.0 $\mu$m launch; its speed is then reduced to zero in 1.0 mm by the air. Using those data and assuming constant accelerations, find the acceleration in terms of g during the launch.

Using the median-median line, what test score would you predict for someone who watches 10 hours of TV per week?
