Homework Answers
Answer: Urine contamination rates are higher in midstream urine that is collected because of increase contamination the accuracy of the result will be low.
If the sample is taken 18 hours earlier then also the accuracy will be not obtained as predetermined samples are unable to give clear results. For example, if the sample of blood is taken for the blood sugar test 18 hours earlier then the results will be not obtained until and unless the blood sample taken has kept in proper storage conditions.
The sample collected by catheterization will produce accuracy if the sample is taken at the right time, in right manners with all the precautions.

This exercise examines the accuracy of various branch predictors for the following repeating pattern (e.g. in a loop) of branch outcomes: T, T, T, NT, T, NT. a. What is the accuracy of always-taken and always-not-taken predictors for this sequence of branch outcomes? b. What is the accuracy of the two-bit predictor for the first five branches in this pattern, i.e. T, T, T, NT, T? Assume that the predictor starts off in the bottom left state from Figure 4.63...

In the context of sampling accuracy “representation” is best described as which one of the following definitions. a) The ability of the employed method to accurately represent the variables included in the study. b) How well the sampling procedure conforms to best practices in the extant literature. c) The accuracy by which the statistical analysis detects direct effects. d) The degree to which a sample has similar characteristics to the population in the properties that are relevant to the study.
