[FinB] Harout wants to improve the performance of the assembly line worker he manages. Currently, the worker produces an average of 750 units per day in baseline. Harout first implements a feedback system where he posts graphs representing the worker’s daily number of units produced. Almost immediately after the feedback system’s implementation, productivity increases to an average of 1,000 units per day. After two weeks at this level, Harout decides to implement a pay-for-performance system with bonuses based on productivity rates. This performance system produces an average of 1,200 units per day for the next 2 weeks. Harout continues implementing these interventions in this same order without randomization and sees similar behavior patterns. Later, Harout implements the performance system immediately following baseline and finds that it is not as effective as it had been during the original testing period. The results of these data are most likely being impacted by which confound?

  In an asymmetric cryptosystem, a PUBLIC key is used to decrypt messages ONLY.

Suppose that a K-bit key is used in the encryption algorithm. If an attacker knows the ciphertext of a message, what is the maximum number of keys the attacker has to attempt in order to find the K-bit key?

[FinB] Bethany, a behavior analyst, is implementing a changing criterion design where their client is trying to increase the ounces of water consumed per day until they reach their goal amount. Bethany reviews the data during one of the sub phases by looking at the level and trend. Which type of analysis is Bethany conducting? 

Why is recruitment of motor units critical during muscle contraction?

[FinB] DJ, a behavior analyst, is conducting a research study in which he will implement a level system for reinforcement for three learners and evaluate the effect of the intervention on chore completion using a multiple baseline across participants design. At the end of the study, DJ evaluates the level, trend, and latency to change for all of the phases. What kind of analysis is DJ conducting?

[FinB] Aurora, a behavior analyst, is consulting at a motor vehicle company to improve accuracy when conducting a specific procedure. She collects baseline data and implements a feedback package to evaluate the impact on accuracy. After a few observations, the results indicate a significant improvement in the employees’ accuracy. However, Aurora was unaware that during the feedback package intervention, a supervisor within the company had placed signs around the office demonstrating how to conduct the specific procedure. Which of the following is likely true of Aurora’s conclusion that the program was primarily responsible for the change in the employees’ behavior?

[FinB] Diego is collecting data on the number of work assignments his employee completes each week at the office. Diego observes his employee for 6 weeks and collects the following weekly data: 17, 11, 11, 13, 9, and 6. What is the trend for this set of data?
