MATHS - Prepare a Hypothesis test population

Case 1

Prepare a Hypothesis test population (Normal and T distribution)

Determine which one lower average with alpha 5%

Data

Pumo 1 (6,6,10,10,5,5,22,18,18,25,25,25,38,38,13,9,9,2,2,2)

Pumo2 (36,36,22,31,30,40,45,37,31,40,40,40,35,40,42,42,42,35,35,40)

Explain the results and use Minitab and paste the results

Case 2

Variance Hypothesis test populations

Prepare a Variance Hypothesis test populations

Collect 20 samples of each population and determine which one has lower consistency with an alpha 5%.

Explain the results and use Minitab and paste the results

Data

Pumo 1 (6,6,10,10,5,5,22,18,18,25,25,25,38,38,13,9,9,2,2,2)

Pumo2 (36,36,22,31,30,40,45,37,31,40,40,40,35,40,42,42,42,35,35,40)

Case3

Linear Regression Analysis

Data

Pumo 1 (6,6,10,10,5,5,22,18,18,25,25,25,38,38,13,9,9,2,2,2)

Pumo2 (36,36,22,31,30,40,45,37,31,40,40,40,35,40,42,42,42,35,35,40)

Prepare Linear Regression Analysis

Collect 20 samples related to the same population and determine if the selected independent variable is affecting the depending variable, Alpha of 5% and Correlation Coefficient

Explain the results and use Minitab and paste the results

Case4

Multiple Linear Regression Analysis

Data

Pumo 1 (6,6,10,10,5,5,22,18,18,25,25,25,38,38,13,9,9,2,2,2)

Pumo2 (36,36,22,31,30,40,45,37,31,40,40,40,35,40,42,42,42,35,35,40)

Same population and determine if the selected independent variable is affecting the depending variable

Use an alpha of 5% and Correlation Coefficient

Explain the results and use Minitab and paste the results
