  • Neither the age of the
    manufacturing equipment and the hours of downtime of the equipment
  • Hours of downtime of the equipment
  • Both the age of the manufacturing equipment and the hours of downtime of the equipment
  • Age of the manufacturing
    equipment

2.
Question 2
A scatter plot in which the plotted points are
clustered approximately into a straight line from the top left to the bottom
right of the graph is displaying which of the following:

1 point

  • Bimodal correlation
  • Positive correlation
  • Negative correlation
  • No correlation

3.
Question 3

pass rate of exams increases with study time, then the correlation coefficient
for the study time versus exams would be:

1 point

correlation?

1 point

    coefficient means that there is not a strong relationship between the variables
  • r can only range from 0 to 1
  • The correlation coefficient can range from -1 to +1
  • The lower the correlation
    coefficient is, the weaker the correlation is

5.
Question 5
In the
equation for basic linear regression, what does the term “b” represent?

5.
Question 5
While performing a hypothesis test, you
calculate a p-value of 0.05. If the
desired level of significance is 0.01 then the conclusion is:

1 point

  • Reject the null hypothesis
    because there is a statistical difference.
  • Reject the null hypothesis
