A study of parental empathy for sensitivity cues and baby temperament (higher scores mean more empathy) was performed. Let x1 be a random variable that represents the score of a mother on an empathy test (as regards her baby). Let x2 be the empathy score of a father. A simple random sample of 28 mother gave a sample mean of x¯1=69.75. Another random sample of 29 fathers gave x¯2=80.71. Assume σ1=10.96 and σ2=9.44.Let μ1 be the population of x1 and let μ2 be the population mean of x2. Find a 97% confidence interval for μ1-μ2.
