During a speed dating session, men and women rated each other on five attributes: ambition, sincerity, intelligence, fun, and shared interest. A difference mean was calculated as -0.35 by subtracting the scores in the following order: MALE RATINGS – FEMALE RATINGS. A confidence interval for this difference mean was calculated as:
-1.25 < μd < 0.55.
Can we support the claim that female ratings are consistently higher?

Ha : μd < 0
Since, mean difference = -0.35 is lies between -1.25 and 0.55, so we fail to reject the null hypothesis.
Answer : No, there, is not statistical significance to female ratings being higher.
