You conduct an experiment in which randomly selected young women are solicited in the street by a good-looking young man who approaches each woman with the following line: "Excuse me! I think you look ravishingly pretty! I just thought you might be happy to know.... I'm going to work now, but do you think we could have a drink somewhere in the afternoon? If you give me your phone number, I'll ring you up." It is recorded whether the woman complies with the man's request and shares her phone number with him. The purpose of the experiment is to find out whether women's decisions are influenced by what the man is wearing. You test a random sample of 50 women under each of the following conditions: (A) the man is wearing an elegant suit, (B) the man is wearing casual clothes but well-known and expensive brands, (C) the man is wearing no-name jeans and a T-shirt. A chi-square test is conducted in SPSS and yields the following output: Compliance Clothes Crosstabulation Count Compliance Total Yes No Pearson Chi-Square Likelihood Ratio Linear-by-Linear Association Elegant suit 12 38 50 Value 7.731 ª Clothes Chi-Square Tests 7.489 6.963 Branded casual df 2 2 1 556 45 50 No-name casual Asymptotic Significance (2-sided) N of Valid Cases 150 a. 0 cells (0.0%) have expected count less than 5.

Transcribed Image Text:You conduct an experiment in which randomly selected young women are solicited in the street by a
good-looking young man who approaches each woman with the following line: "Excuse me! I think
you look ravishingly pretty! I just thought you might be happy to know... I'm going to work now, but
do you think we could have a drink somewhere in the afternoon? If you give me your phone number,
I'll ring you up." It is recorded whether the woman complies with the man's request and shares her
phone number with him. The purpose of the experiment is to find out whether women's decisions
are influenced by what the man is wearing. You test a random sample of 50 women under each of
the following conditions: (A) the man is wearing an elegant suit, (B) the man is wearing casual clothes
but well-known and expensive brands, (C) the man is wearing no-name jeans and a T-shirt.
A chi-square test is conducted in SPSS and yields the following output:

Expert Solution
Step 1:-
In this question we want to check whether women's decisions are influenced by what the man is wearing.
We state the hypothesis,
Null hypothesis; H0: There is no association between women's decisions and clothes wearing by man (women's decisions are not influenced by what the man is wearing.)
Alternatively hypothesis, H0: There is a association between women's decisions and clothes wearing by man (women's decisions are influenced by what the man is wearing.)
