Given:

The given bivariate data is(1,6),(3,2), and (2,4).

Calculation:

First determine

Find the sample variance

Find sample standard deviation.

For covariance

Where n = number of ordered pairs.

n=3

Find the correlation coefficient r using the formula

Hence the value of correlation coefficient r = -1.

The two-way table summarizes data from an experiment comparing the effectiveness of three different diets (A, B, and C) on weight loss. Researchers randomly assigned 300 volunteer subjects to the three diets. The response variable was whether each subject lost weight over a 1-year period.

Suppose we randomly select one of the subjects from the experiment. Show that the events "Diet B" and "Lost weight" are independent.

You were asked about advantages of using box plots and dot plots to describe and compare distributions of scores. Do you think the advantages you found would exist not only for these data, but for numerical data in general? Explain.

Understanding the Concepts and Skills

Suppose that, for a sample of pairs of observations from two variables, the linear correlation coefficient, r , is negative. Does this result necessarily imply that the variables are negatively linearly correlated? Explain.
