WebNov 4, 2024 · Explanation: To find the z score for 0.05, we have to refer the Area Under Normal Distribution Table. z scores are given along the 1st column and 1st row. The table is populated with probability values or area under normal curve. The given value is significance level. We have to find its corresponding confidence level. To do that -
WebThe z score can be determined for both the sample data and population data. The z score formulas that are used in the z score table are given as follows: Z score for population data: z = x−μ σ x − μ σ μ μ = population mean σ σ = population standard deviation x = raw score Z score for sample data: z = x−¯¯x S x − x ¯ S ¯¯¯x x ¯ = sample mean
