A Pew Research Center survey asked respondents if they would rather live in a place with a slower pace of life or a place with a faster pace of life. The survey also asked the respondent’s gender. Consider the following sample data.
Gender | ||||
Preferred Pace of Life | Male | Female | ||
Slower | 229 | 217 | ||
No Preference | 23 | 23 | ||
Faster | 88 | 50 |
a. Is the preferred pace of life independent of gender? Using a .05 level of significance, what is the -value?
Compute the value of the χ2 test statistic (to 3 decimals).
The p-value = ??
What is your conclusion?
(Cannot conclude/Conclude) that the preferred pace of life is not independent of gender.
b. What are the percentage responses for each gender (to 1 decimal)?

Discuss any differences between the preferences of men and women.
(Men only/Women only/Both men and women) prefer a slower pace of life. Women have a higher preference for a (slower/faster) pace of life, while men have a higher preference for a (slower/faster) pace of life.
a) Applying chi square test:
Expected | Ei=row total*column total/grand total | Male | Female | Total |
Slower | 240.70 | 205.30 | 446 | |
No preference | 24.83 | 21.17 | 46 | |
Faster | 74.48 | 63.52 | 138 | |
total | 340 | 290 | 630 | |
chi square χ2 | =(Oi-Ei)2/Ei | Male | Female | Total |
Slower | 0.569 | 0.667 | 1.235 | |
No preference | 0.134 | 0.157 | 0.292 | |
Faster | 2.456 | 2.879 | 5.335 | |
total | 3.159 | 3.703 | 6.8616 |
test statistic X2 =6.862
p value =0.0324
Conclude that the preferred pace of life is not independent of gender.
b)
Preferred Pace of Life | Male | Female |
Slower | 67.4% | 74.8% |
No Preference | 6.8% | 7.9% |
Faster | 25.9% | 17.2% |
Both men and women prefer a slower pace of life. Women have a higher preference for a slower pace of life, while men have a higher preference for a faster pace of life.

Sociologists have conducted much interesting research on gender stereotypes in American society. A curious aspect of sterotypes is that people tend to perceive differences between groups to be greater than they actually are. This suggests, for example, thr when asked about the heights of men and women, survey respondents would tend to percieve men to be taller than women. suppose you wanted to test this notion that individuals perceive a greater height difference between men and women than exists in...
