Test Scores on a Standardized Test from Samples of Students $\begin{array}{ll}&UA&UB\\\text { Sample Size } & 28&41 \\\text { Average Test Score } & 84&82 \\\text { variance }& 64&100\end{array}$

question 44

Short Answer

Test scores on a standardized test from samples of students from two universities are given below.
$\begin{array}{ll}&UA&UB\\\text { Sample Size } & 28&41 \\\text { Average Test Score } & 84&82 \\\text { variance }& 64&100\end{array}$ Provide a 98% confidence interval estimate for the difference between the test scores of the two universities.

Definitions:

Fixed-Ratio

In the context of reinforcement learning, it describes a schedule where a response is reinforced only after a specified number of responses have occurred, leading to a high, steady rate of responding.

Variable-Ratio

A reinforcement schedule in which the number of responses required for a reward varies around an average, making the reinforcement unpredictable and typically leading to high and stable response rates.

DRH

A differential reinforcement of high rates of behavior schedule where reinforcement is contingent on responses being made at or above a certain rate.

DRO

A behavioral intervention technique known as Differential Reinforcement of Other behavior, where reinforcement is delivered for any behavior other than a target behavior.
