Obtain data for two groups of 100 data that you produce yourself by using Minitab . Name it as A-Group and B-Group. ( The data may be integers )

1) At the meaning levels you will determine; Construct and interpret a double-sided and a one-sided confidence interval for the A-Group and B-Group data separately, for the mean and variances of populations.

2-) At the meaning levels you will determine; Prepare a two-sided and one-sided hypothesis test for A-Group and B-Group data separately, for the mean and variance of populations, and interpret the results.

3) At the level of meaning you will determine; Test and interpret whether there is a significant difference between the A-Group and B-Group populations means. Calculate the P-value approximately.

4) At the level of meaning you will determine; Compare the variances of A-Group and B-Group data with populations and calculate the P-value approximately

5) Condider only one of the A-Group or B-Group data as the dependent variable (Y) and time (X) as an independent variable, creating a single-variable linear regression equation and interpret the coefficients. ( HANDWRITTEN not with a computer program except data generation)
