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 a = 0.05.

Listed below are the overhead widths (in cm) of seals measured from photographs and the weights (in kg) of the seals. Construct a scatterplot, find the value of the linear correlation coefficient r, and find the critical values of r using a = 0.05. Is there sufficient evidence to conclude that there is a linear correlation between overhead widths of seals from photographs and the weights of the seals?

54 wild bears are anesthetized, and then their waits
and chest sizes were measured and listed in a data set. Results are
shown in the accompanying display. Is there sufficient evidence to
support the claim that there is a linear correlation between the
weights of bears and their chest sizes? When measuring an
anesthetized bear, is it easier to measure chest size and weight?
If so, does it appear that a measured chest size can be used to
predict the...

. A data set about speed dating includes "like" ratings of male dates made by the female dates. The summary statistics are n. 185, 783,8 2 27. Use a 0.05 significance level to test the claim that the population mean of such ratings is less than 8.00. Assume that a simple random sample has been selected. Identify the null and alternative hypotheses, test statistic, P-value and state the final conclusion that addresses the original claim What are the null and...
