STATE The toco toucan Ramphastos toco is the largest member of the toucan family and possesses the largest beak relative to body size of all birds This exaggerated feature has been interpreted in various ways such as being a refined adaptation for feeding However the large surface area may also be an important mechanism for radiating heat and hence cooling the bird as outdoor temperature increases Here are data for beak heat loss as a percent of total body heat loss at various temperatures in degrees Celsius Temperature C 15 16 17 18 19 20 21 22 Percent heat loss 32 34 35 33 37 46 55 51 from beak Temperature C 23 24 25 26 27 28 29 30 Percent heat loss from beak 43 52 45 53 58 60 62 62 access the complete data set click the link for your referred software format cel Minitab14 18 Minitab18 JMP SPSS TI R Mac KT PC TXT CSV Crunchlt rom a graph in G J Tattersall et al Heat exchange from the toucan bill als a controllable vascular thermal radiator Science 325 2009 pp 470 O Macmillan Learning PLAN Plan to create a scatterplot and compute a numerical correlation metric to analyze the relationship between percent heat loss from beak response variable and temperature explanatory variable SOLVE Use software of your choice to create a scatterplot of percent heat loss from beak versus temperature Examine the scatterplot and describe the pattern Identify the correct interpretation of the relationship between temperature and percent heat loss based on the scatterplot r There is a weak negative linear relationship between temperature and heat loss There is a strong positive linear relationship between temperature and heat loss There is a moderately strong positive nonlinear relationship between temperature and heat loss O There is a weak negative linear relationship between temperature and heat loss Calculate the correlation r between temperature and the percent of heat loss from beak Provide your answer with precision to three decimal places
