Use the data from previous exercise and find Bonferroni-corrected intervals for all three comparisons assuming an overall confidence level of 95 percent, using an individual confidence level of 98.33 percent. Then state whether the means are significantly different based on whether the intervals capture 0 or not. Compare your conclusions with the conclusions in earlier exercise.

Complete and balance the following overall equations. a) $\mathrm{KOH}(\mathrm{aq})+\mathrm{HNO}_3(\mathrm{aq}) \rightarrow$ b) $\mathrm{Ba}(\mathrm{OH})_2($ aq $)+\mathrm{HCl}($ aq $) \rightarrow$ c) $\mathrm{NaOH}(\mathrm{aq})+\mathrm{H}_3 \mathrm{PO}_4(\mathrm{aq}) \rightarrow$ d) $\mathrm{Ca}(\mathrm{OH})_2$ (aq) $+\mathrm{H}_3 \mathrm{PO}_4$ (aq) $\rightarrow$

The wave heights h in the open sea depend on the speed v of the wind and the length of time t that the wind has been blowing at that speed. Values of the function h=f(v, t) are recorded in feet in Table 4.

What is the meaning of the function h=f(v, 30)? Describe the behavior of this function.

TABLE 4

The displacement from equilibrium caused by a wave on a string is given by $y(x, t)=(-0.00200 \mathrm{~m}) \sin \left[\left(40.0 \mathrm{~m}^{-1}\right) x-\left(800 . \mathrm{s}^{-1}\right) t\right]$. For this wave, what are the (e) speed?

Show that the total energy released in the protonproton chain is $26.7 \mathrm{MeV}$, considering the overall effect in ${ }^1 \mathrm{H}+{ }^1 \mathrm{H} \rightarrow{ }^2 \mathrm{H}+e^{+}+v_{\mathrm{e}},{ }^1 \mathrm{H}+{ }^2 \mathrm{H} \rightarrow{ }^3 \mathrm{He}+\gamma$, and ${ }^3 \mathrm{He}+{ }^3 \mathrm{He} \rightarrow{ }^4 \mathrm{He}+{ }^1 \mathrm{H}+{ }^1 \mathrm{H}$. Be sure to include the annihilation energy.

In testing $9$ sedans, an automotive publication rated each on 13 different characteristics, including ride, handling, and driver comfort. Each vehicle also received an overall rating. Scores for each were as follows.

$$\begin{array}{ccccc} \boldsymbol{y}= & & & \boldsymbol{x}_3= \\ \text { Car } & \begin{array}{c} \text { Overall } \\ \text { Rating } \end{array} & x_1= & \begin{array}{c} x_2= \\ \text { Ride } \\ \text { Handling } \end{array} & \begin{array}{c} \text { Driver } \\ \text { Comfort } \end{array} \\ \hline 1 & 85 & 8 & 7 & 7 \\ 2 & 88 & 8 & 8 & 8 \\ 3 & 85 & 6 & 8 & 7 \\ 4 & 85 & 8 & 7 & 9 \\ 5 & 97 & 9 & 9 & 9 \\ 6 & 86 & 8 & 8 & 9 \\ 7 & 90 & 9 & 6 & 9 \\ 8 & 84 & 7 & 8 & 7 \\ 9 & 94 & 8 & 9 & 8 \end{array}$$

b. Interpret the $y$-intercept and partial regression coefficients.

Jenny must sit four papers for an exam. The mean of the first three papers Jenny has sat is 72%. (a) If she wants to get an overall mean of at least 75%, what is the lowest mark she can get in her fourth paper? (b) What is the highest possible mean she can get over all four papers?

Wave frequency is measured in which unit?

A. decibel

B. hertz

C. meter

D. second

How does the envelope of the wave pattern vary with distance in (a) a lossless medium and (b) a lossy medium?

An amoeba is 0.305 cm away from the 0.300 cm- focal length objective lens of a microscope. (a) Where is the image formed by the objective lens? (b) What is this image’s magnification? (c) An eyepiece with a 2.00-cm focal length is placed 20.0 cm from the objective. Where is the final image? (d) What angular magnification is produced by the eyepiece? (e) What is the overall magnification?

If the work function of a material is such that red light of wave-length 700 nm just barely initiates the photoelectric effect, what must the maximum kinetic energy of ejected electrons be when violet light of wavelength 400 nm illuminates the material?

Consider the periodic function

$$F(t)=\left\{\begin{array}{ll} \sin \omega t, & 0<t<\pi / \omega \\ 0, & \pi / \omega<t<2 \pi / \omega \end{array}\right.$$

which represents the positive portions of a sine function. (Such a function represents, for example, the output of a half-wave rectifying circuit.) Find the Fourier representation and plot the sum of the first four terms.

Coal gasification is a multi-step process to convert coal into cleaner-burning gaseous fuels. In one step, a certain coal sample reacts with superheated steam:
$\mathrm{C}($ coal $)+\mathrm{H}_2 \mathrm{O}(g) \longrightarrow \mathrm{CO}(g)+\mathrm{H}_2(g) \quad \Delta H_{\mathrm{rxn}}^{\circ}=129.7 \mathrm{~kJ}$
(b) Calculate $\Delta H_{\mathrm{rxn}}^{\circ}$ for this overall change.
