The accompanying table lists the "attribute" ratings made by a random sample of participants in a speed dating session. Each attribute rating is the sum of the ratings of five attributes (sincerity, intelligence, fun, ambition, shared interests). Use a 0.05 significance level to test the claim that there is a difference between female attribute ratings and male attribute ratings.

Part 1

In this example, d is the mean value of the differences d for the population of all pairs of data, where each individual difference d is defined as the rating of the male minus the rating of the female. What are the null and alternative hypotheses for the hypothesis test?

H0 : d = 0

H1 : d 0

(Type integers or decimals. Do not round.)

Part 2

Identify the test statistic.

t =

(Round to two decimal places as needed.)

Part 3

Identify the P-value.

P-value =

(Round to three decimal places as needed.)

Part 4

What is the conclusion based on the hypothesis test?

Since the P-value is _____________ the significance level, _____________ the null hypothesis. There ________ sufficient evidence to support the claim that there is a difference between female attribute ratings and male attribute ratings.
