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 35 mothers gave a sample mean of x1 = 69.04. Another random sample of 38 fathers
gave x2 = 57.68. Assume that 1 = 11.83 and 2 = 11.73.
(a)
Let 1 be the population mean of x1 and let 2 be the population mean of x2. Find a 99%
confidence interval for 1 2. (Round your answers to two decimal places.)
lower limit:
Upper limit:
(b)
Examine the confidence interval and explain what it means in the context of this problem. Does
the confidence interval contain all positive, all negative, or both positive and negative numbers?
What does this tell you about the relationship between average empathy scores for mothers
compared with those for fathers at the 99% confidence level?
