Your bank has made several loans, each of which comes with some amount of risk. This risk assessment is done using an ML system. This system provides a prediction for which of the loans will default and which will not. As you analyze last year’s performance you want to figure out how often your system was right. Below are the results:   Defaulted Not defaulted Predicted to default 23 9 Predicted to no default 4 132   Use the information in the precision for both “default” and “not default.” Round to the nearest hundredth (keep answer in decimal form). Using the information in the table, calculate accuracy, precision, and recall for both “default” and “not default.”  Round to the nearest hundreth. Precision for “default” is . Precision for “not default” is .

Can a machine learning model that is bias also be fair?

The nurse has just hung a new IV bag of 1000 milliliters of Normal saline. A 500 milliliter bolus of IV normal saline is to be infused over 30 minutes per IV pump.   At how many milliliters would the nurse set the volume to be infused?

You have a PCA pump. The patient has hydromorphone  5  mg in 30 ml. The patient is to receive a bolus of 1.0  milligrams. How many milliliters should the nurse program the pump to inject?

In a population, freckles are inherited as a dominant trait. Individuals who are homozygous recessive lack freckles. If 1% of the population lacks freckles, and the population is in Hardy-Weinberg equilibrium at this locus, what percentage of the next generation will lack freckles?

The Hardy-Weinberg equilibrium requires all of the following except

Behavioral isolation prevents speciation by

Lake Tanganyika, the oldest of the Great Ancient Lakes in East Africa, harbors about 250 species of cichlid fish which evolved from a single ancestor into a diverse group of species that each exploits the resources of the lake environment in a different way. The evolution of one species of cichlid into many species within Lake Tanganyika is an example of
