A quality control engineer is interested in the mean length of sheet insulation being cut automatically by machine. The desired length of the insulation is 12 metres. It is known that the standard deviation in the cutting length is 0.15 metres. A sample of 144 cut sheets yield a mean length of 12.14 metres. This sample will be used to obtain a 90% confidence interval for the mean length cut by machine. What are the two limits of the confidence...

A quality engineer analyzed the paint job on the Lexus IS350 model at the Toyota plant in Woodstock. 250 cars were analyzed. The drying time (in hours) and colour of paint was recorded. dentify the variable(s) in the study, (ii) explain the type of data for each variable in the study (e.g., categorical and ordinal, continuous or discrete, etc.), (ii) identify the observational unit, and (iv) determine the sample size 1. For a list of positive numbers, is it possible...

[Should we build a wind farm?] Wind Power has been the most popular alternative energy choice in recent years. One of the key determinants for choosing a location for a wind farm is whether the site has enough wind. To produce enough energy using current technology, the site should have an annual average wind speed exceeding 9.25 miles per hour, according to the Wind Energy Association. One candidate site in southern California was monitored for a year, with wind speeds...

Investigators working on commericially cultivating shrimp are interested in determining the best conditions in which for them to grow. They are interested in knowing what impact water temperature (either 25 C, 30 C) and the salinity level (10 %, 25 % and 40 %) have on the growth of shrimp. Three replicates were used for each of the 6 possible treatment combinations. Post-larval shrimp were placed in each of the 18 tanks and fed the same amount of food. After...

You may need to use the appropriate appendix table or technology to answer this question. Barron's reported that the average number of weeks an individual is unemployed is 17.5 weeks. Assume that for the population of all unemployed individuals the population mean length of unemployment is 17.5 weeks and that the population standard deviation is 6 weeks. Suppose you would like to select a sample of 60 unemployed individuals for a follow-up study. (a) Show the sampling distribution of X,...

Please help ASAP please.
Let X represent the full height of a certain species of tree. Assume that X has a normal probability distribution with mean 219.5 ft and standard deviation 62.5 ft You intend to measure a random sample of n 187 trees. The bell curve below represents the distibution of these sample means. The scale on the horizontal axis is the standard error of the sampling distribution Complete the indicated boxes, correct to two decimal places Points possible:...
