Need explanation, answers, six step hypothesis test along with minitab answers and instructions.

A group of 15 students are randomly selected and for each student the number of absences from class each week and the grade point average are recorded. The data collected will be used to determine the extent of a potential relationship between the two variables.

Absences 5 65 4 3 3 4 21 2 1 21 1 0

GPA 0.500.781.001.121.431.481.272.002.502.582.873.003.333.72 3.95

a) Use Minitab to generate a scatterplot of the data and the correlation between the variables.

b) Test at the 5% significance level for a statistically significant linear relationship the between two variables. Include all six steps of the hypothesis test.

c) Determine the coefficient of determination. What does it indicate about the relationship

between the variables?

d) Use Minitab to determine the equation of the Least Squares Regression Line. Use the least squares fit line to predict the GPA for a student who misses 3 classes a week.
