Is linear regression inferential statistics

WitrynaExample 3: Find the z score using descriptive and inferential statistics for the given data. Population mean 100, sample mean 120, population variance 49 and size 10. Solution: Inferential statistics is used to find the z score of the data. The formula is given as follows: z = x−μ σ x − μ σ. Standard deviation = √49 49 = 7.
