An LED light bulb manufacturer claims that the average lifespan of its 60-watt LED light bulbs is 33,000 hours. A corporate watchdog group is suspicious of the company's claim and thinks that the true average lifespan of the 60-watt LED light bulbs produced by the company may be less than the advertised 33,000 hours. The group collected and tested a random sample of 291 light bulbs and found the average lifespan of the sample was 32,943 hours. Use the p-value method to test the hypothesis that the mean lifespan of this brand of 60-watt LED light bulb is less than 33,000 hours, using $\alpha$ = 0.005. Assume the standard deviation of the lifespan of all such light bulbs is known to be 530 hours. State the null and alternative hypothesis for this test. $H_0: \mu = 33000$ $H_1: \mu < 33000$ Determine if this test is left-tailed, right-tailed, or two-tailed. O two-tailed O right-tailed $\checkmark$ left-tailed Should the standard normal ($z$) distribution or Student's ($t$) distribution be used for this test? O The standard normal ($z$) distribution should be used O The Student's $t$ distribution should be used $\checkmark$ Determine the test statistic for the hypothesis test. Round the solution to two decimal places. -0.36 Determine the p-value for the hypothesis test. Round the solution to four decimal places. 0.359 x

Use the General Social Survey (GSS) to find the data. Nominal Respondents' gun ownership was measured using one indicator that asked, "Do you happen to have in your home (IF HOUSE: or garage) any guns or revolvers?" The original coding format for this qualitative, nominal level outcome variable was: (1) Favor/Yes, (2) Oppose/No, (3) "Don't Know," and (4) No Answer. Initially, attitude toward respondents' gun ownership/attitude toward abortion for any reason/fear at night when walking within one mile of home possessed cases; however, after missing data were removed, a new dummy coded variable was created, which possessed valid cases. The category of interest for the recoded version of attitude toward respondents' gun ownership/attitude toward abortion for any reason/fear at night when walking within one mile of home is "Favor/Yes" (%). The fewest number/majority of valid cases came from respondents who selected "Oppose/No" (%).

8.2 ** Although the main topic of this chapter is the motion of two particles subject to no external forces, many of the ideas [for example, the splitting of the Lagrangian L into two independent pieces L = Lcm + Lrel as in Equation (8.13)] extend easily to more general situations. To illustrate this, consider the following: Two masses m1 and m2 move in a uniform gravitational field g and interact via a potential energy U(r). (a) Show that the Lagrangian can be decomposed as in (8.13). (b) Write down Lagrange's equations for the three CM coordinates X, Y, Z and describe the motion of the CM. Write down the three Lagrange equations for the relative coordinates and show clearly that the motion of r is the same as that of a single particle of mass equal to the reduced mass ?, with position r and potential energy U(r).

4) Describe the difference between hot and cold working in terms of energy required for deformation, surface finish and property changes. 5) What are the specific differences between gray and nodular cast iron in terms of composition, microstructure and properties? 6) The steel alloys 1040 and 4340 have significantly different hardenabilities. Describe why this would be important for a large component that will undergo a quenching heat treatment. 7) Discuss the steps in producing a clay- based ceramic from slip clay. Be specific and describe all steps and their effect on the microstructure of the material. Specifically why is the original material called slip clay? 8) Glass can undergo a tempering process. What is the purpose of tempering glass? Describe the process and how it affects the properties of the material.
