Homework Statement
One class application of correlation and regression involves the association between the temperature and the number of times cricket chirps in a minute. Listed below are numbers of chirps in 1 minute and the corresponding temperature in degrees Fahrenheit.
Chirps in 1 min 882 1188 1104 864 1200 1032 960 900
temperature 69.7 93.3 84.3 76.3 88.6 82.6 71.6 79.6
i. Is there sufficient evidence to conclude that there is an association between the number of chirps in a minute and the temperature?
ii. Find the equation of the straight line that best fits the sample data.
iii. If a cricket chirps 1234 times in 1 minute, what is the best predicted value for the temperature?
iv. What percentage of the variation in temperature can be explained by the variation in the cricket chirp rate?
v. Can the correlation/regression results be used to show that changes in temperature cause changes in the cricket chirp rate?
