Question

英语翻译
(a) Calculate an analysis of variance table and test the null hypothesis that the number
of revolutions per minute has no effect on the fluid flow rate.
(b) Are you happy with your conclusion?Why or why not?
(c) Calculate a 90% upper confidence limit for the error variance σ2.
14.Pedestrian light experiment (Larry Lesher,1985)
Larry Lesher ran this experiment in order to determine whether pushing a certain pedes-trian light button had an effect on how long he had to wait before the pedestrian light showed “walk.” The treatment factor of interest was the number of pushes of the but-ton,and 13 observations were taken for each of 0,1,2,and 3 pushes of the button.The waiting times for the “walk” sign for the first 32 observations in the order collected are shown in Table 3.12,giving r0=7,r1=r2=10,r3=5 (where the levels of the treatment factor are coded as 0,1,2,3 for simplicity).The observations were taken as close together as possible on a Saturday in February 1985.
(a) Plot the waiting times against the number of pushes of the button.What does the
plot show?
(b) Construct an analysis of variance table and test the null hypothesis that the number
of pushes of the pedestrian button has no effect on the waiting time for the “walk”
sign.
(c) Estimate the mean waiting time for each number of pushes and the corresponding
variance.
(d) Estimate the contrast τ0− (τ1+ τ2+ τ3)/3,which compares the effect of no pushes
of the button with the average effect of pushing the button once,twice,or three
times.
15.Trout experiment (Gutsell,1951,Biometrics)
The data in Table 3.13 show the measurements of hemoglobin (grams per 100 ml) in
the blood of brown trout.The trout were placed at random in four different troughs.

Answer 1

(a) 计算方差分析表和测试空值假设的数目每分钟有没有上过排放率的影响.
(b) 感到满意你的结论呢?为什么或为什么不呢?(c) 计算误差超差 σ2 90%上限的信任限制.14.行人光实验 （Larry Lesher,1985年）拉里 · Lesher 做这个实验,以确定是否推某些强势徒步轻按钮了影响多长时间,他不得不等待行人灯显示"走".感兴趣的治疗因素是但吨级、 推送的数目和 13 的意见采取的 0、 1、 2 和 3 的推送,按钮的每个.轮候时间对焦虑 32 观测所收集的顺序"步行"标志所示表 3.12,给予 r0 = 7,r1 = r2 = 10、 r3 = 的 5 （治疗因子水平编码为 0、 1、 2、 3 为简单起见）.意见采取了彼此接近,尽量在 1985 年 2 月在星期六.
(a) 阴谋反对按下的按钮的数目的轮候时间.干什么显示的阴谋?
(b) 构造的方差分析表和测试空值假设的数目行人按钮的推送的并不影响"走"的轮候时间签名.
(c) 估计每个下的数目和相应的平均轮候时间方差.
(d) 估计对比 τ0− （τ1 + τ2 + τ3） / 3,它比较 no 的作用将推按钮,用推的按钮一次、 两次,或三个的平均效果倍.
15.鳟试验 （Gutsell,1951 年,生物识别）3.13 表中的数据显示的度量值的血红蛋白 （克每 100 毫升）布朗鳟鱼的血液.鳟鱼被随意放在四个不同的槽中.
