Essay

You are studying two normally distributed populations with equal variances.A random sample of size 10 is taken from each population.The sample from the first population gives the following measurements: 16,14,19,18,19,20,15,18,17,18.The sample from the second population gives the following measurements: 13,19,14,17,21,14,15,10,13,15.Compute the 95% confidence interval for the difference between two population means

Definitions:

Encoding Specificity

The tendency for memory of information to be improved if related information (such as surroundings or physiological state) that is available when the memory is first formed is also available when the memory is being retrieved.

Retrieval Conditions

Retrieval conditions refer to the various factors or contexts that can affect the ability to recall memories, including the environment, emotional state, and cues present during the memory recall.

Morse Code

A method used in telecommunication to encode text characters as standardized sequences of two different signal durations, called dots and dashes.

Encoding Specificity

Encoding specificity refers to the principle that cues and contexts specific to a particular memory will be most effective in helping us recall it.
