Please answer a-e

A classic experiment by Dutton & Aron (1974) examined men's attraction to a female they met in either one of two conditions: on a high unstable, shaky bridge or on a low sturdy bridge. Later, they rated the attractiveness of the woman. The following data is a generated replica of this study. Attractiveness was rated as 1-10 with 10 being very attractive. The researchers want to evaluate how the independent variable (bridge height) affects attractiveness ratings. More specifically, they predict that those men in the higher bridge condition will rate the woman as being more attractive. a.) State your null and alternative hypotheses. b.) What are your degrees of freedom and critical value(s) given an alpha = .05 level? d.) Calculate your test statistic. e.) Given the alpha level of alpha = .05, what would the researchers conclude about bridge height and attractiveness ratings? Write a conclusionary statement and be sure to report your results as it would appear in an APA compliant manuscript (e.g. t(df) = t_ p

Explanation / Answer

1) Ho: Mean( High Bridge) =Mean( Low Bridge)

Ha : Mean( High Bridge) >= Mean( Low Bridge)

B,D,G are shown below.

P = 0.0304

E)

Since, P-value is less than 0.05, researchers would conclude that this is significant and thus, null hypothesis can be rejected. High bridge men have a higher attractiveness for women.

Difference -2.250 Standard error 1.000 95% CI -4.2753 to -0.2247 t-statistic -2.251 DF 37 Significance level

P = 0.0304
