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 random sample of 33 mothers gave a sample mean of x1 = 69.72. Another random sample of 38 fathers gave x2 = 57.68. Assume that Population Standard Deviation1 = 11.97 and Population Standard Deviation2
