Transcribed Image Text:A data set includes weights of garbage discarded in one week from 62 different households. The paired weights of paper and glass were used to obtain the results
shown to the right. Is there sufficient evidence to support the claim that there is a linear correlation between weights of discarded paper and glass? Use a significance
level of α = 0.05.
Click here to view a table of critical values for the correlation coefficient.
Determine the null and alternative hypotheses.

State the conclusion.
Because the absolute value of the test statistic is
the positive critical value, there
