Thermal endurance tests were performed to study therelationship between temperature and lifetime of poly-ester enameled wire ("Thermal Endurance ofPolyester Enameled Wires Using Twisted WireSpecimens," IEEE Trans. Insulation, 1965: 38-44),resulting in the following data.Temp200200200200200200Lifetime5933 54044947496333583878Temp220220220220220220Lifetime15611494747768609777Temp240240240240240240Lifetime258299144180209184a. Does a scatterplot of the data suggest a linear probabi-listic relationship between lifetime and temperature?b. What model is implied by a linear relationshipbetween expected ln(lifetime) and 1/temperature?Does a scatterplot of the transformed data appearconsistent with this relationship?Estimate the parameters of the model suggested inpart (b). What lifetime would you predict for a tem-с.perature of 220?d. Because there are multiple observations at eachx value, the method in Exercise 14 can be used to testthe null hypothesis that states that the model sugges-ted in part (b) is correct.

Lesson 14: Using Normal Distributions for Exper. Destry Orceu Rescarchers are tagging sharks using two different types of devices and want to know if the devices affect the heart rate of tho sharks. They tag one aroup of 8 sharks with a small device that collects a small amount of data and thoy tag another group of 8 sharks with a larger device that collects a large amount of data. They then measure the mean heart rate of the different groups and find that the difference in means is 2.5 beats per minute. Rescarchers run 1,000 simulations regrouping the data into 2 groups at random and record the differences in means…
Total plasma volume is important in determining the required plasma component in blood replacement therapy for a person undergoing surgery. Plasma volume is influenced by the overall health and physical activity of an individual. Suppose that a random sample of 43 male firefighters are tested and that they have a plasma volume sample mean of x = 37.5 ml/kg (milliliters plasma per kilogram body weight). Assume that σ = 7.50 ml/kg for the distribution of blood plasma. (a) Find a 99% confidence interval for the population mean blood plasma volume in male firefighters. What is the margin of error?

An article in the ACI Materials Journal (Vol. 84, 1987, pp. 213-216) describes several experiments investigating the rodding of concrete to remove trapped air. A 3-inch x 6-inch cylinder was used, and the number of times this rod was used is the design variable. The resulting compressive strength of the concrete specimen is the response. The data are shown in the following table.
