3.18. A manufacturer of television sets is interested in theeffect on tube conductivity of four different types of coatingfor color picture tubes. A completely randomized experimentis conducted and the following conductivity data areobtained:Coating Type123424143152134129Conductivity150137132132141149136127146143127129(a) Is there a difference in conductivity due to coatingtype? Use a = 0.05.(b) Estimate the overall mean and the treatment effects.(c) Compute a 95 percent confidence interval estimateof the mean of coating type 4. Compute a 99 percentconfidence interval estimate of the mean differencebetween coating types 1 and 4. (d) Test all pairs of means using the Fisher LSD methodwith a = 0.05.(e) Use the graphical method discussed in Section 3.5.3 tocompare the means. Which coating type produces thehighest conductivity?(f) Assuming that coating type 4 is currently in use, whatare your recommendations to the manufacturer? Wewish to minimize conductivity.

Tsunami Waves and BreakwatersThis is a continuation of Exercise 16. Breakwaters affect wave height by reducing energy. See Figure 5.30. If a tsunami wave of height H in a channel of width W encounters a breakwater that narrows the channel to a width w, then the height h of the wave beyond the breakwater is given by h=HR0.5, where R is the width ratio R=w/W. a. Suppose a wave of height 8 feet in a channel of width 5000feet encounters a breakwater that narrows the channel to 3000feet. What is the height of the wave beyond the breakwater? b. If a channel width is cut in half by a breakwater, what is the effect on wave height? 16. Height of Tsunami WavesWhen waves generated by tsunamis approach shore, the height of the waves generally increases. Understanding the factors that contribute to this increase can aid in controlling potential damage to areas at risk. Greens law tells how water depth affects the height of a tsunami wave. If a tsunami wave has height H at an ocean depth D, and the wave travels to a location with water depth d, then the new height h of the wave is given by h=HR0.25, where R is the water depth ratio given by R=D/d. a. Calculate the height of a tsunami wave in water 25feet deep if its height is 3feet at its point of origin in water 15,000feet deep. b. If water depth decreases by half, the depth ratio R is doubled. How is the height of the tsunami wave affected?

Provide the following: IV (with 2 levels): DV: Ha: Ho: Solve the t-test below. A recent study examined the drinking behaviors of undergraduate college students (male and female freshmen). Each participant was asked how many alcoholic beverages they consumed during the past 7 days. The researchers wish to determine if there is a difference in the drinking habits of males and females in this age group. Female Male 9 13 5 9 5 7 9 11 8 10 3 5 5 6 2 10 1 16 7 12 Which type of test will you run? What it the IV? What is the DV? What are the statistical hypotheses (Null and Alternative)? What is the t-obtained value? Make a decision about the null hypothesis (reject the Ho or Fail to reject the Ho). Based on the interpretation of the results, what can you say about sex and drinking habits?

The students' teacher has a video camera, which is not available for use in thne experimental procedure described above. The teacher uses the camera and video analysis software to generate the data shown in the table below. The table shows the sphere's horizontal and vertical displacements x and y, as measured from the location of the sphere's launch point. Vertical Displacement y (m) 0.065 Horizontal Displacement x (m) 0.50 1.00 0.245 1.50 0.560 2.00 0.990 The students want to use the teacher's data to determine whether the claim that y is proportional to x2 is true. Determine the appropriate quantities to be graphed to determine whether the claim is true. Plot the appropriate quantities using "Graphical Analysis" and upload a copy of your graph, including clearly labeled axes with units.
