A study of parental empathy for sensitivity cues and baby temperament (higher scores mean more empathy) was performed. Letx1be a random variable that represents the score of a mother on an empathy test (as regards her baby). Letx2be the empathy score of a father. A simple random sample of 32 mother gave a sample mean ofx1=61.22x. Another random sample of 29 fathers gavex2=58.24x
Assume1=12.43 and2=6.39
Let1be the population ofx1and let2be the population mean ofx2. Find a 97% confidence interval for1-2. (Round answers to two decimal places.)
