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 31 mothers gave a sample mean 68.4. Another random sample of 35 fathers gave a sample mean of 59.1. Assume that o₁ = 11.8 and ₂ = 10.5. Let u be the population mean of x₁ and let u₂ be the population mean of x2. Find a 99% confidence interval for ₁ - ₂. (Round your answers to 2 decimal places.) Lower Limit Upper Limit (b) Choose the correct conclusion Owe can not say that the mothers have a higher mean empathy score. OWe can say with 99% confidence that the mothers have a higher mean empathy score. OWe can say with 99% confidence that the fathers have a higher mean empathy score.
