Astudy conducted at the university of denver investigated whether babies take longer to learn to crawl in cold months, when they are often bundled in clothes that restrict their movement, than in warmer months.^18 infants born during the study year were split into twelve groups, one for each birth month. we consider the average crawling age of babies in each group against the average temperature when the babies are six months old (that's when babies often begin trying to crawl). temperature is measured in degrees fahrenheit (degree f) and age is measured in weeks. (a) describe the relationship between temperature and crawling age. (b) how would the relationship change if temperature was measured in degrees celsius (degree c) and age was measured in months? (c) the correlation between temperature in degree f and age in weeks was r = -0.70. if we converted the temperature to degree c and age to months, what would the correlation be?
