Suppose the reaction temperature X (in C) in a certain chemical process has a uniform distribution with A 5 and B 5. a. Compute P(X 0). b. Compute P( 2.5 X 2.5). c. Compute P( 2 X 3). d. For k satisfying 5 k k 4 5, compute P(k X k 4).
Chapter 1 Section 1 Variable-a characteristic/attribute that can assume different values Data- values that the variables can assume Population- all subjects undergoing a study Parameter- measure obtained from the population data Uses Greek Letters to categorize Sample- a group selected from the population, to make the study more concentrated Statistic- a measure that is obtained from the sample data Uses the Alphabet to categorize Descriptive Statistics- the collection, organization as well as summarization of data Basically sums up what you’ve collected and makes it easier to understand Inferential Statistics- generalizes a known sample data to the unknown population data
