The national institute of standards and technology (nist) supplies "standard materials" whose physical properties are supposed to be known. for example, you can buy from nist a liquid whose electrical conductivity is supposed to be 5. (the units for conductivity are microsiemens per centimeter. distilled water has conductivity 0.5.) of course, no measurement is exactly correct. nist knows the variability of its measurements very well, so it is quite realistic to assume that the population of all measurements of the same liquid has the normal distribution with mean μ
μ
equal to the true conductivity and standard deviation σ
σ
= 0.2. here are 6 measurements on the same standard liquid, which is supposed to have conductivity 5:
5.32 4.88 5.10 4.73 5.15 4.75
nist wants to give the buyer of this liquid a 90% confidence interval for its true conductivity. what is this interval?

Graph the line that represents a proportional relationship between d and t with the property that an increase of 33 units in t corresponds to an increase of 44 units in d. what is the unit rate of change of dd with respect to t? (that is, a change of 11 unit in t will correspond to a change of how many units in d? )
