Plus-Minus Notation. There are times where you'd like to write an expression such as 3±2. This expression has two results, one from adding the numbers and another from subtracting the numbers. In this case, 3±2 results in the numbers 3+2=5 and 3-2=1 1. Evaluate 5±7 In Statistics + notation can be seen in formulas when constructing the confidence intervals for some parameters. 2. Evaluate 3.41±√√4.6 rounded to the nearest hundredth For example: Confident Interval for population mean can be written as ± (sample mean Margin of Error) or (±E) Confidence Interval for population proportion can be written as ± (sample proportion Margin of Error) or (±E) 3. Find confidence interval for the population mean if sample mean =68 and Margin of Error E=0.8225 (67.1775, 68.8225) 4. Construct confidence interval for population proportion if sample proportion P = 0.6 and Margin of Error E-0.036 (0.564, 0.636)
