In statistics, Xi represents an individual data point or observation within a dataset. It is commonly used to denote the ith data point in a sequence of data. The subscript i is used to differentiate between different data points in the dataset, with i typically ranging from 1 to n, where n is the total number of data points. Xi is a fundamental concept in statistical analysis and is essential for calculating various statistical measures and conducting data analysis.

Random error.

It means that there is a probability of 0.0968 that an observation as extreme as this occurred purely by chance.

1) personal observation 2) statistical report 3) break even analysis 4)budgetary control

No. One observation will normally get you onevalue, not a set of values. Also, to be precise, the observation is the act of observing; the value is the result of the observation, not the observation itself.
