In the confidence interval method the sample data must come from a population that is normally distributed with no outliers.
A confidence interval is a range of values derived from observable data at a desired level of confidence that may include the parameter's true value. The confidence level, such as a 95% confidence level, refers to the accuracy of the estimating process rather than the degree of assurance that the computed confidence interval accurately represents the true value of the parameter under investigation. Confidence intervals are typically written as (some value) ± (a range). The range can be expressed as a percentage or as a real amount. The equation used to determine the confidence interval varies depending on which standard deviation is known.

Answer:
The answer is the items at the end of the list.
Explanation:
The student in the example is more likely to remember the items at the end of the list, due to a phenomenon called the recency effect: we will remember best the most recent information. At the same time, this is related to the serial-position effect, which states that the order of the items in a list influences the way we remember them. More specifically, <u>we remember items at the end and the beginning more easily</u>.
