- What is the Discrete Variable Standard Deviation for the following numbers: x = 0 and P(X = x) = 0.56 x = 1 and P(X = x) = 0.15 x = 2 and P(X = x) = 0.11 x = 3 and P(X = x) = 0.13 x = 4 and P(X = x) = 0.05 Level of difficulty = 2 of 2 Please format to 4 decimal places. Answer:· A drug company is considering marketing a new local anesthetic. The effective time of the anesthetic the drug company is currently producing has a normal distribution with an average of 7.4 minutes with a standard devia- tion of 1.2 minutes. The chemistry of the new anesthetic is such that the effective time sho- uld be normal with the same standard devia- tion, but the mean effective time may be lo- wer. If it is lower, the drug company will market the new anesthetic; otherwise, they will continue to produce the older one. A sam- ple of size 36 results in a sample mean of 7.1. A hypothesis test will be done to help make the decision.
