What is the answer for Q2?
Chapter 9 Problem A: The drying time of a certain type of paint under specified test conditions is normally distributed with a = 9. Let u denote the ture average drying time when the additive is used. The hypotheses Ho: x= 75 versus He: x<75 are to be tested using a random sample of n = 25 observations. ---- 1. Refer to Problem A. If I = 72.3, what is the conclusion using a...

The drying time of a certain type of paint under specified test conditions is known to be normally distributed with mean value 75 min and standard deviation 9 min. Chemists have proposed a new additive designed to decrease average drying time. It is believed that drying times with this additive will remain normally distributed with σ = 9. Because of the expense associated with the additive, evidence should strongly suggest an improvement in average drying time before such a conclusion...

I would like some assistance correcting an issue I am having with this assignment. Once a finite state automaton (FSA) is designed, its transition diagram can be translated in a straightforward manner into program code. However, this translation process is considerably tedious if the FSA is large and troublesome if the design is modified. The reason is that the transition information and mechanism are combined in the translation. To do it differently, we can design a general data structure such...
