A study conducted at the University of Denver investigated whether babies take longer to learn to crawlin cold months, when they are often bundled in clothes that restrict their movement, than in warmermonths. Infants born during the study year were split into twelve groups, one for each birth month. Weconsider the average crawling age of babies in each group against the average temperature when thebabies are six months old (that's when babies often begin trying to crawl). Temperature is measured indegrees Fahrenheit and age is measured in weeks.3433323130-293040506070Temperature (F)a) Describe the relationship between temperature and crawling age. Choose all answers that apply.There is strong, negative, linear relationship between termperature and crawling agenThere is a somewhat moderate, negative, linear relationship between temperature and crawlingagenThere is a moderate, positive, linear relationship between the temperature and crawling ageThe point at the bottom should be taken under considerationb) How would the relationship change if temperature was measured in degrees Celsius and age wasmeasured in months?O The correlation coefficient between the two variables would be largerO Changing the units will not change the form, direction or strength of the relationship between thetwo variablesThe correlation coefficient between the two variables would be smallerc) The correlation between temperature in degrees F and age in weeks was r =the temperature to degrees C and age to months, what would the correlation be?0.7. If we convertedAvg. crawling age (weeks)

Given that, Let 'X' be the random variable represents the Crawling Age (in weeks) Let 'Y' be the…

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).
